Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604726, here are decompositions:

3 + 31604723 = 31604726
7 + 31604719 = 31604726
37 + 31604689 = 31604726
79 + 31604647 = 31604726
193 + 31604533 = 31604726
229 + 31604497 = 31604726
367 + 31604359 = 31604726
379 + 31604347 = 31604726

Showing the first eight; more decompositions exist.
