Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604546, here are decompositions:

13 + 31604533 = 31604546
37 + 31604509 = 31604546
163 + 31604383 = 31604546
199 + 31604347 = 31604546
283 + 31604263 = 31604546
409 + 31604137 = 31604546
613 + 31603933 = 31604546
829 + 31603717 = 31604546

Showing the first eight; more decompositions exist.
