Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604198, here are decompositions:

7 + 31604191 = 31604198
61 + 31604137 = 31604198
211 + 31603987 = 31604198
397 + 31603801 = 31604198
487 + 31603711 = 31604198
541 + 31603657 = 31604198
631 + 31603567 = 31604198
709 + 31603489 = 31604198

Showing the first eight; more decompositions exist.
