Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535662, here are decompositions:

5 + 31535657 = 31535662
23 + 31535639 = 31535662
29 + 31535633 = 31535662
71 + 31535591 = 31535662
113 + 31535549 = 31535662
233 + 31535429 = 31535662
239 + 31535423 = 31535662
251 + 31535411 = 31535662

Showing the first eight; more decompositions exist.
