Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604192, here are decompositions:

3 + 31604189 = 31604192
313 + 31603879 = 31604192
349 + 31603843 = 31604192
673 + 31603519 = 31604192
811 + 31603381 = 31604192
883 + 31603309 = 31604192
1051 + 31603141 = 31604192
1069 + 31603123 = 31604192

Showing the first eight; more decompositions exist.
