Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604004, here are decompositions:

13 + 31603991 = 31604004
17 + 31603987 = 31604004
71 + 31603933 = 31604004
73 + 31603931 = 31604004
127 + 31603877 = 31604004
283 + 31603721 = 31604004
293 + 31603711 = 31604004
347 + 31603657 = 31604004

Showing the first eight; more decompositions exist.
