Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615804, here are decompositions:

13 + 8615791 = 8615804
37 + 8615767 = 8615804
97 + 8615707 = 8615804
151 + 8615653 = 8615804
181 + 8615623 = 8615804
277 + 8615527 = 8615804
313 + 8615491 = 8615804
331 + 8615473 = 8615804

Showing the first eight; more decompositions exist.
