Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700938, here are decompositions:

7 + 8700931 = 8700938
67 + 8700871 = 8700938
139 + 8700799 = 8700938
229 + 8700709 = 8700938
241 + 8700697 = 8700938
349 + 8700589 = 8700938
409 + 8700529 = 8700938
577 + 8700361 = 8700938

Showing the first eight; more decompositions exist.
