Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535664, here are decompositions:

7 + 31535657 = 31535664
31 + 31535633 = 31535664
71 + 31535593 = 31535664
73 + 31535591 = 31535664
113 + 31535551 = 31535664
197 + 31535467 = 31535664
241 + 31535423 = 31535664
283 + 31535381 = 31535664

Showing the first eight; more decompositions exist.
