Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615544, here are decompositions:

5 + 8615539 = 8615544
17 + 8615527 = 8615544
31 + 8615513 = 8615544
37 + 8615507 = 8615544
53 + 8615491 = 8615544
71 + 8615473 = 8615544
73 + 8615471 = 8615544
83 + 8615461 = 8615544

Showing the first eight; more decompositions exist.
