Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613584, here are decompositions:

3 + 31613581 = 31613584
5 + 31613579 = 31613584
71 + 31613513 = 31613584
173 + 31613411 = 31613584
227 + 31613357 = 31613584
251 + 31613333 = 31613584
293 + 31613291 = 31613584
467 + 31613117 = 31613584

Showing the first eight; more decompositions exist.
