Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604998, here are decompositions:

11 + 31604987 = 31604998
149 + 31604849 = 31604998
239 + 31604759 = 31604998
251 + 31604747 = 31604998
311 + 31604687 = 31604998
317 + 31604681 = 31604998
389 + 31604609 = 31604998
641 + 31604357 = 31604998

Showing the first eight; more decompositions exist.
