Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604484, here are decompositions:

31 + 31604453 = 31604484
97 + 31604387 = 31604484
101 + 31604383 = 31604484
113 + 31604371 = 31604484
127 + 31604357 = 31604484
137 + 31604347 = 31604484
173 + 31604311 = 31604484
181 + 31604303 = 31604484

Showing the first eight; more decompositions exist.
