Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604366, here are decompositions:

7 + 31604359 = 31604366
19 + 31604347 = 31604366
67 + 31604299 = 31604366
103 + 31604263 = 31604366
139 + 31604227 = 31604366
229 + 31604137 = 31604366
379 + 31603987 = 31604366
433 + 31603933 = 31604366

Showing the first eight; more decompositions exist.
