Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604076, here are decompositions:

19 + 31604057 = 31604076
43 + 31604033 = 31604076
89 + 31603987 = 31604076
157 + 31603919 = 31604076
197 + 31603879 = 31604076
199 + 31603877 = 31604076
233 + 31603843 = 31604076
337 + 31603739 = 31604076

Showing the first eight; more decompositions exist.
