Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604354, here are decompositions:

7 + 31604347 = 31604354
13 + 31604341 = 31604354
43 + 31604311 = 31604354
73 + 31604281 = 31604354
127 + 31604227 = 31604354
163 + 31604191 = 31604354
367 + 31603987 = 31604354
421 + 31603933 = 31604354

Showing the first eight; more decompositions exist.
