Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535650, here are decompositions:

11 + 31535639 = 31535650
17 + 31535633 = 31535650
59 + 31535591 = 31535650
101 + 31535549 = 31535650
227 + 31535423 = 31535650
233 + 31535417 = 31535650
239 + 31535411 = 31535650
269 + 31535381 = 31535650

Showing the first eight; more decompositions exist.
