Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535608, here are decompositions:

17 + 31535591 = 31535608
59 + 31535549 = 31535608
179 + 31535429 = 31535608
191 + 31535417 = 31535608
197 + 31535411 = 31535608
227 + 31535381 = 31535608
281 + 31535327 = 31535608
389 + 31535219 = 31535608

Showing the first eight; more decompositions exist.
