Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604654, here are decompositions:

7 + 31604647 = 31604654
13 + 31604641 = 31604654
43 + 31604611 = 31604654
97 + 31604557 = 31604654
157 + 31604497 = 31604654
271 + 31604383 = 31604654
283 + 31604371 = 31604654
307 + 31604347 = 31604654

Showing the first eight; more decompositions exist.
