Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627938, here are decompositions:

29 + 8627909 = 8627938
41 + 8627897 = 8627938
71 + 8627867 = 8627938
131 + 8627807 = 8627938
197 + 8627741 = 8627938
239 + 8627699 = 8627938
257 + 8627681 = 8627938
311 + 8627627 = 8627938

Showing the first eight; more decompositions exist.
