Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493422, here are decompositions:

3 + 31493419 = 31493422
83 + 31493339 = 31493422
101 + 31493321 = 31493422
131 + 31493291 = 31493422
173 + 31493249 = 31493422
251 + 31493171 = 31493422
269 + 31493153 = 31493422
353 + 31493069 = 31493422

Showing the first eight; more decompositions exist.
