Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535656, here are decompositions:

17 + 31535639 = 31535656
23 + 31535633 = 31535656
107 + 31535549 = 31535656
227 + 31535429 = 31535656
233 + 31535423 = 31535656
239 + 31535417 = 31535656
443 + 31535213 = 31535656
599 + 31535057 = 31535656

Showing the first eight; more decompositions exist.
