Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712122, here are decompositions:

31 + 8712091 = 8712122
103 + 8712019 = 8712122
151 + 8711971 = 8712122
271 + 8711851 = 8712122
373 + 8711749 = 8712122
379 + 8711743 = 8712122
439 + 8711683 = 8712122
571 + 8711551 = 8712122

Showing the first eight; more decompositions exist.
