Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613694, here are decompositions:

67 + 31613627 = 31613694
71 + 31613623 = 31613694
113 + 31613581 = 31613694
181 + 31613513 = 31613694
257 + 31613437 = 31613694
283 + 31613411 = 31613694
293 + 31613401 = 31613694
311 + 31613383 = 31613694

Showing the first eight; more decompositions exist.
