Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613634, here are decompositions:

5 + 31613629 = 31613634
7 + 31613627 = 31613634
11 + 31613623 = 31613634
53 + 31613581 = 31613634
83 + 31613551 = 31613634
193 + 31613441 = 31613634
197 + 31613437 = 31613634
223 + 31613411 = 31613634

Showing the first eight; more decompositions exist.
