Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615532, here are decompositions:

5 + 8615527 = 8615532
19 + 8615513 = 8615532
41 + 8615491 = 8615532
53 + 8615479 = 8615532
59 + 8615473 = 8615532
61 + 8615471 = 8615532
71 + 8615461 = 8615532
109 + 8615423 = 8615532

Showing the first eight; more decompositions exist.
