Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604204, here are decompositions:

13 + 31604191 = 31604204
67 + 31604137 = 31604204
271 + 31603933 = 31604204
487 + 31603717 = 31604204
523 + 31603681 = 31604204
547 + 31603657 = 31604204
811 + 31603393 = 31604204
823 + 31603381 = 31604204

Showing the first eight; more decompositions exist.
