Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604756, here are decompositions:

13 + 31604743 = 31604756
37 + 31604719 = 31604756
67 + 31604689 = 31604756
109 + 31604647 = 31604756
199 + 31604557 = 31604756
223 + 31604533 = 31604756
373 + 31604383 = 31604756
397 + 31604359 = 31604756

Showing the first eight; more decompositions exist.
