Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604126, here are decompositions:

139 + 31603987 = 31604126
193 + 31603933 = 31604126
283 + 31603843 = 31604126
409 + 31603717 = 31604126
607 + 31603519 = 31604126
733 + 31603393 = 31604126
877 + 31603249 = 31604126
1117 + 31603009 = 31604126

Showing the first eight; more decompositions exist.
