Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535422, here are decompositions:

3 + 31535419 = 31535422
5 + 31535417 = 31535422
11 + 31535411 = 31535422
41 + 31535381 = 31535422
101 + 31535321 = 31535422
239 + 31535183 = 31535422
251 + 31535171 = 31535422
389 + 31535033 = 31535422

Showing the first eight; more decompositions exist.
