Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608452, here are decompositions:

3 + 31608449 = 31608452
103 + 31608349 = 31608452
151 + 31608301 = 31608452
181 + 31608271 = 31608452
283 + 31608169 = 31608452
439 + 31608013 = 31608452
613 + 31607839 = 31608452
661 + 31607791 = 31608452

Showing the first eight; more decompositions exist.
