Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615998, here are decompositions:

107 + 8615891 = 8615998
227 + 8615771 = 8615998
431 + 8615567 = 8615998
491 + 8615507 = 8615998
719 + 8615279 = 8615998
761 + 8615237 = 8615998
821 + 8615177 = 8615998
947 + 8615051 = 8615998

Showing the first eight; more decompositions exist.
