Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608436, here are decompositions:

173 + 31608263 = 31608436
269 + 31608167 = 31608436
389 + 31608047 = 31608436
467 + 31607969 = 31608436
569 + 31607867 = 31608436
647 + 31607789 = 31608436
653 + 31607783 = 31608436
719 + 31607717 = 31608436

Showing the first eight; more decompositions exist.
