Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631604, here are decompositions:

5 + 8631599 = 8631604
71 + 8631533 = 8631604
263 + 8631341 = 8631604
353 + 8631251 = 8631604
521 + 8631083 = 8631604
563 + 8631041 = 8631604
587 + 8631017 = 8631604
593 + 8631011 = 8631604

Showing the first eight; more decompositions exist.
