Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522456, here are decompositions:

5 + 31522451 = 31522456
23 + 31522433 = 31522456
83 + 31522373 = 31522456
179 + 31522277 = 31522456
227 + 31522229 = 31522456
353 + 31522103 = 31522456
443 + 31522013 = 31522456
479 + 31521977 = 31522456

Showing the first eight; more decompositions exist.
