Consider the primes arranged in their natural order 2,3, 5,7, It is conjectured that beginning with 3, every other prime can be composed of the addition and subtraction of 3 1 +2, 7 1-2+ 3+5, F1+2+3+ 5-7 + 11. all smaller primes (and 1), each taken once. For example: 13 1 +2-3-5+7+11 x 1 Show that this also holds for 19, 29, 37, and 43.
