Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712938, here are decompositions:

7 + 8712931 = 8712938
19 + 8712919 = 8712938
79 + 8712859 = 8712938
181 + 8712757 = 8712938
211 + 8712727 = 8712938
229 + 8712709 = 8712938
277 + 8712661 = 8712938
337 + 8712601 = 8712938

Showing the first eight; more decompositions exist.
