Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604728, here are decompositions:

31 + 8604697 = 8604728
61 + 8604667 = 8604728
79 + 8604649 = 8604728
199 + 8604529 = 8604728
241 + 8604487 = 8604728
409 + 8604319 = 8604728
421 + 8604307 = 8604728
487 + 8604241 = 8604728

Showing the first eight; more decompositions exist.
