Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712038, here are decompositions:

19 + 8712019 = 8712038
67 + 8711971 = 8712038
151 + 8711887 = 8712038
241 + 8711797 = 8712038
271 + 8711767 = 8712038
331 + 8711707 = 8712038
421 + 8711617 = 8712038
487 + 8711551 = 8712038

Showing the first eight; more decompositions exist.
