Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613650, here are decompositions:

11 + 31613639 = 31613650
23 + 31613627 = 31613650
71 + 31613579 = 31613650
137 + 31613513 = 31613650
239 + 31613411 = 31613650
251 + 31613399 = 31613650
293 + 31613357 = 31613650
317 + 31613333 = 31613650

Showing the first eight; more decompositions exist.
