Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638604, here are decompositions:

61 + 8638543 = 8638604
127 + 8638477 = 8638604
151 + 8638453 = 8638604
157 + 8638447 = 8638604
193 + 8638411 = 8638604
223 + 8638381 = 8638604
277 + 8638327 = 8638604
313 + 8638291 = 8638604

Showing the first eight; more decompositions exist.
