Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722756, here are decompositions:

17 + 8722739 = 8722756
83 + 8722673 = 8722756
113 + 8722643 = 8722756
149 + 8722607 = 8722756
239 + 8722517 = 8722756
257 + 8722499 = 8722756
347 + 8722409 = 8722756
389 + 8722367 = 8722756

Showing the first eight; more decompositions exist.
