Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604456, here are decompositions:

3 + 31604453 = 31604456
73 + 31604383 = 31604456
97 + 31604359 = 31604456
109 + 31604347 = 31604456
157 + 31604299 = 31604456
193 + 31604263 = 31604456
229 + 31604227 = 31604456
523 + 31603933 = 31604456

Showing the first eight; more decompositions exist.
