Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604088, here are decompositions:

31 + 31604057 = 31604088
37 + 31604051 = 31604088
97 + 31603991 = 31604088
101 + 31603987 = 31604088
157 + 31603931 = 31604088
199 + 31603889 = 31604088
211 + 31603877 = 31604088
331 + 31603757 = 31604088

Showing the first eight; more decompositions exist.
