Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604426, here are decompositions:

43 + 31604383 = 31604426
67 + 31604359 = 31604426
79 + 31604347 = 31604426
127 + 31604299 = 31604426
163 + 31604263 = 31604426
199 + 31604227 = 31604426
439 + 31603987 = 31604426
547 + 31603879 = 31604426

Showing the first eight; more decompositions exist.
