Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615518, here are decompositions:

5 + 8615513 = 8615518
11 + 8615507 = 8615518
47 + 8615471 = 8615518
239 + 8615279 = 8615518
251 + 8615267 = 8615518
257 + 8615261 = 8615518
281 + 8615237 = 8615518
419 + 8615099 = 8615518

Showing the first eight; more decompositions exist.
