Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604408, here are decompositions:

37 + 31604371 = 31604408
61 + 31604347 = 31604408
67 + 31604341 = 31604408
97 + 31604311 = 31604408
109 + 31604299 = 31604408
127 + 31604281 = 31604408
181 + 31604227 = 31604408
271 + 31604137 = 31604408

Showing the first eight; more decompositions exist.
