Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604348, here are decompositions:

7 + 31604341 = 31604348
37 + 31604311 = 31604348
67 + 31604281 = 31604348
157 + 31604191 = 31604348
211 + 31604137 = 31604348
547 + 31603801 = 31604348
631 + 31603717 = 31604348
691 + 31603657 = 31604348

Showing the first eight; more decompositions exist.
