Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613574, here are decompositions:

23 + 31613551 = 31613574
61 + 31613513 = 31613574
137 + 31613437 = 31613574
163 + 31613411 = 31613574
173 + 31613401 = 31613574
191 + 31613383 = 31613574
197 + 31613377 = 31613574
233 + 31613341 = 31613574

Showing the first eight; more decompositions exist.
