Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604074, here are decompositions:

17 + 31604057 = 31604074
23 + 31604051 = 31604074
41 + 31604033 = 31604074
83 + 31603991 = 31604074
197 + 31603877 = 31604074
317 + 31603757 = 31604074
353 + 31603721 = 31604074
431 + 31603643 = 31604074

Showing the first eight; more decompositions exist.
