Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604136, here are decompositions:

7 + 31604129 = 31604136
37 + 31604099 = 31604136
79 + 31604057 = 31604136
103 + 31604033 = 31604136
149 + 31603987 = 31604136
257 + 31603879 = 31604136
293 + 31603843 = 31604136
307 + 31603829 = 31604136

Showing the first eight; more decompositions exist.
