Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533650, here are decompositions:

13 + 31533637 = 31533650
19 + 31533631 = 31533650
37 + 31533613 = 31533650
79 + 31533571 = 31533650
103 + 31533547 = 31533650
139 + 31533511 = 31533650
151 + 31533499 = 31533650
199 + 31533451 = 31533650

Showing the first eight; more decompositions exist.
