Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645604, here are decompositions:

7 + 8645597 = 8645604
17 + 8645587 = 8645604
61 + 8645543 = 8645604
113 + 8645491 = 8645604
127 + 8645477 = 8645604
173 + 8645431 = 8645604
197 + 8645407 = 8645604
223 + 8645381 = 8645604

Showing the first eight; more decompositions exist.
