Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604684, here are decompositions:

3 + 31604681 = 31604684
37 + 31604647 = 31604684
43 + 31604641 = 31604684
73 + 31604611 = 31604684
127 + 31604557 = 31604684
151 + 31604533 = 31604684
313 + 31604371 = 31604684
337 + 31604347 = 31604684

Showing the first eight; more decompositions exist.
