Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596650, here are decompositions:

13 + 31596637 = 31596650
37 + 31596613 = 31596650
67 + 31596583 = 31596650
79 + 31596571 = 31596650
97 + 31596553 = 31596650
109 + 31596541 = 31596650
139 + 31596511 = 31596650
271 + 31596379 = 31596650

Showing the first eight; more decompositions exist.
