Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604162, here are decompositions:

229 + 31603933 = 31604162
283 + 31603879 = 31604162
643 + 31603519 = 31604162
673 + 31603489 = 31604162
769 + 31603393 = 31604162
853 + 31603309 = 31604162
1021 + 31603141 = 31604162
1039 + 31603123 = 31604162

Showing the first eight; more decompositions exist.
