Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615744, here are decompositions:

37 + 8615707 = 8615744
157 + 8615587 = 8615744
271 + 8615473 = 8615744
283 + 8615461 = 8615744
367 + 8615377 = 8615744
421 + 8615323 = 8615744
457 + 8615287 = 8615744
547 + 8615197 = 8615744

Showing the first eight; more decompositions exist.
