Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712086, here are decompositions:

67 + 8712019 = 8712086
199 + 8711887 = 8712086
223 + 8711863 = 8712086
337 + 8711749 = 8712086
349 + 8711737 = 8712086
367 + 8711719 = 8712086
379 + 8711707 = 8712086
433 + 8711653 = 8712086

Showing the first eight; more decompositions exist.
