Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604, here are decompositions:

3 + 31601 = 31604
31 + 31573 = 31604
37 + 31567 = 31604
61 + 31543 = 31604
73 + 31531 = 31604
127 + 31477 = 31604
211 + 31393 = 31604
271 + 31333 = 31604

Showing the first eight; more decompositions exist.
