Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522538, here are decompositions:

79 + 31522459 = 31522538
97 + 31522441 = 31522538
127 + 31522411 = 31522538
181 + 31522357 = 31522538
199 + 31522339 = 31522538
211 + 31522327 = 31522538
241 + 31522297 = 31522538
331 + 31522207 = 31522538

Showing the first eight; more decompositions exist.
