Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656978, here are decompositions:

59 + 8656919 = 8656978
107 + 8656871 = 8656978
131 + 8656847 = 8656978
149 + 8656829 = 8656978
191 + 8656787 = 8656978
251 + 8656727 = 8656978
257 + 8656721 = 8656978
311 + 8656667 = 8656978

Showing the first eight; more decompositions exist.
