Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613604, here are decompositions:

23 + 31613581 = 31613604
53 + 31613551 = 31613604
163 + 31613441 = 31613604
167 + 31613437 = 31613604
193 + 31613411 = 31613604
227 + 31613377 = 31613604
263 + 31613341 = 31613604
271 + 31613333 = 31613604

Showing the first eight; more decompositions exist.
