Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523422, here are decompositions:

3 + 31523419 = 31523422
11 + 31523411 = 31523422
23 + 31523399 = 31523422
41 + 31523381 = 31523422
113 + 31523309 = 31523422
179 + 31523243 = 31523422
191 + 31523231 = 31523422
311 + 31523111 = 31523422

Showing the first eight; more decompositions exist.
