Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604762, here are decompositions:

3 + 31604759 = 31604762
19 + 31604743 = 31604762
31 + 31604731 = 31604762
43 + 31604719 = 31604762
73 + 31604689 = 31604762
151 + 31604611 = 31604762
229 + 31604533 = 31604762
379 + 31604383 = 31604762

Showing the first eight; more decompositions exist.
