Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604630, here are decompositions:

3 + 31604627 = 31604630
19 + 31604611 = 31604630
73 + 31604557 = 31604630
97 + 31604533 = 31604630
271 + 31604359 = 31604630
283 + 31604347 = 31604630
331 + 31604299 = 31604630
349 + 31604281 = 31604630

Showing the first eight; more decompositions exist.
