Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615550, here are decompositions:

7 + 8615543 = 8615550
11 + 8615539 = 8615550
23 + 8615527 = 8615550
37 + 8615513 = 8615550
43 + 8615507 = 8615550
59 + 8615491 = 8615550
71 + 8615479 = 8615550
79 + 8615471 = 8615550

Showing the first eight; more decompositions exist.
