Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522342, here are decompositions:

3 + 31522339 = 31522342
11 + 31522331 = 31522342
29 + 31522313 = 31522342
101 + 31522241 = 31522342
113 + 31522229 = 31522342
239 + 31522103 = 31522342
251 + 31522091 = 31522342
281 + 31522061 = 31522342

Showing the first eight; more decompositions exist.
