Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604754, here are decompositions:

7 + 31604747 = 31604754
11 + 31604743 = 31604754
23 + 31604731 = 31604754
31 + 31604723 = 31604754
67 + 31604687 = 31604754
73 + 31604681 = 31604754
107 + 31604647 = 31604754
113 + 31604641 = 31604754

Showing the first eight; more decompositions exist.
