Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604474, here are decompositions:

103 + 31604371 = 31604474
127 + 31604347 = 31604474
163 + 31604311 = 31604474
193 + 31604281 = 31604474
211 + 31604263 = 31604474
283 + 31604191 = 31604474
337 + 31604137 = 31604474
487 + 31603987 = 31604474

Showing the first eight; more decompositions exist.
