Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604732, here are decompositions:

13 + 31604719 = 31604732
43 + 31604689 = 31604732
199 + 31604533 = 31604732
223 + 31604509 = 31604732
349 + 31604383 = 31604732
373 + 31604359 = 31604732
421 + 31604311 = 31604732
433 + 31604299 = 31604732

Showing the first eight; more decompositions exist.
