Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604432, here are decompositions:

61 + 31604371 = 31604432
73 + 31604359 = 31604432
151 + 31604281 = 31604432
241 + 31604191 = 31604432
499 + 31603933 = 31604432
631 + 31603801 = 31604432
751 + 31603681 = 31604432
823 + 31603609 = 31604432

Showing the first eight; more decompositions exist.
