Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596620, here are decompositions:

7 + 31596613 = 31596620
37 + 31596583 = 31596620
67 + 31596553 = 31596620
79 + 31596541 = 31596620
109 + 31596511 = 31596620
229 + 31596391 = 31596620
241 + 31596379 = 31596620
313 + 31596307 = 31596620

Showing the first eight; more decompositions exist.
