Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712518, here are decompositions:

97 + 8712421 = 8712518
151 + 8712367 = 8712518
181 + 8712337 = 8712518
211 + 8712307 = 8712518
337 + 8712181 = 8712518
349 + 8712169 = 8712518
499 + 8712019 = 8712518
547 + 8711971 = 8712518

Showing the first eight; more decompositions exist.
