Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604848, here are decompositions:

59 + 31604789 = 31604848
89 + 31604759 = 31604848
101 + 31604747 = 31604848
167 + 31604681 = 31604848
239 + 31604609 = 31604848
347 + 31604501 = 31604848
461 + 31604387 = 31604848
491 + 31604357 = 31604848

Showing the first eight; more decompositions exist.
