Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535716, here are decompositions:

59 + 31535657 = 31535716
83 + 31535633 = 31535716
167 + 31535549 = 31535716
293 + 31535423 = 31535716
389 + 31535327 = 31535716
503 + 31535213 = 31535716
593 + 31535123 = 31535716
659 + 31535057 = 31535716

Showing the first eight; more decompositions exist.
