Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604548, here are decompositions:

47 + 31604501 = 31604548
191 + 31604357 = 31604548
251 + 31604297 = 31604548
359 + 31604189 = 31604548
419 + 31604129 = 31604548
449 + 31604099 = 31604548
491 + 31604057 = 31604548
557 + 31603991 = 31604548

Showing the first eight; more decompositions exist.
