Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657604, here are decompositions:

37 + 8657567 = 8657604
41 + 8657563 = 8657604
47 + 8657557 = 8657604
71 + 8657533 = 8657604
101 + 8657503 = 8657604
173 + 8657431 = 8657604
181 + 8657423 = 8657604
223 + 8657381 = 8657604

Showing the first eight; more decompositions exist.
