Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535896, here are decompositions:

17 + 31535879 = 31535896
149 + 31535747 = 31535896
179 + 31535717 = 31535896
239 + 31535657 = 31535896
257 + 31535639 = 31535896
263 + 31535633 = 31535896
347 + 31535549 = 31535896
467 + 31535429 = 31535896

Showing the first eight; more decompositions exist.
