Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522326, here are decompositions:

13 + 31522313 = 31522326
29 + 31522297 = 31522326
79 + 31522247 = 31522326
83 + 31522243 = 31522326
97 + 31522229 = 31522326
107 + 31522219 = 31522326
197 + 31522129 = 31522326
223 + 31522103 = 31522326

Showing the first eight; more decompositions exist.
