Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620696, here are decompositions:

13 + 31620683 = 31620696
17 + 31620679 = 31620696
97 + 31620599 = 31620696
127 + 31620569 = 31620696
179 + 31620517 = 31620696
197 + 31620499 = 31620696
199 + 31620497 = 31620696
223 + 31620473 = 31620696

Showing the first eight; more decompositions exist.
