Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535692, here are decompositions:

11 + 31535681 = 31535692
53 + 31535639 = 31535692
59 + 31535633 = 31535692
101 + 31535591 = 31535692
263 + 31535429 = 31535692
269 + 31535423 = 31535692
281 + 31535411 = 31535692
311 + 31535381 = 31535692

Showing the first eight; more decompositions exist.
