Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604460, here are decompositions:

7 + 31604453 = 31604460
73 + 31604387 = 31604460
89 + 31604371 = 31604460
101 + 31604359 = 31604460
103 + 31604357 = 31604460
113 + 31604347 = 31604460
149 + 31604311 = 31604460
157 + 31604303 = 31604460

Showing the first eight; more decompositions exist.
