Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604012, here are decompositions:

79 + 31603933 = 31604012
211 + 31603801 = 31604012
331 + 31603681 = 31604012
523 + 31603489 = 31604012
619 + 31603393 = 31604012
631 + 31603381 = 31604012
751 + 31603261 = 31604012
1039 + 31602973 = 31604012

Showing the first eight; more decompositions exist.
