Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535674, here are decompositions:

3 + 31535671 = 31535674
17 + 31535657 = 31535674
41 + 31535633 = 31535674
83 + 31535591 = 31535674
251 + 31535423 = 31535674
257 + 31535417 = 31535674
263 + 31535411 = 31535674
293 + 31535381 = 31535674

Showing the first eight; more decompositions exist.
