Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615522, here are decompositions:

31 + 8615491 = 8615522
43 + 8615479 = 8615522
61 + 8615461 = 8615522
199 + 8615323 = 8615522
373 + 8615149 = 8615522
439 + 8615083 = 8615522
571 + 8614951 = 8615522
673 + 8614849 = 8615522

Showing the first eight; more decompositions exist.
