Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604992, here are decompositions:

5 + 31604987 = 31604992
59 + 31604933 = 31604992
233 + 31604759 = 31604992
269 + 31604723 = 31604992
311 + 31604681 = 31604992
383 + 31604609 = 31604992
389 + 31604603 = 31604992
431 + 31604561 = 31604992

Showing the first eight; more decompositions exist.
