Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613632, here are decompositions:

3 + 31613629 = 31613632
5 + 31613627 = 31613632
53 + 31613579 = 31613632
191 + 31613441 = 31613632
233 + 31613399 = 31613632
383 + 31613249 = 31613632
389 + 31613243 = 31613632
461 + 31613171 = 31613632

Showing the first eight; more decompositions exist.
