Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615670, here are decompositions:

13 + 8615657 = 8615670
17 + 8615653 = 8615670
47 + 8615623 = 8615670
79 + 8615591 = 8615670
83 + 8615587 = 8615670
103 + 8615567 = 8615670
127 + 8615543 = 8615670
131 + 8615539 = 8615670

Showing the first eight; more decompositions exist.
