Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522356, here are decompositions:

17 + 31522339 = 31522356
29 + 31522327 = 31522356
43 + 31522313 = 31522356
59 + 31522297 = 31522356
79 + 31522277 = 31522356
109 + 31522247 = 31522356
113 + 31522243 = 31522356
127 + 31522229 = 31522356

Showing the first eight; more decompositions exist.
