Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522258, here are decompositions:

11 + 31522247 = 31522258
17 + 31522241 = 31522258
29 + 31522229 = 31522258
167 + 31522091 = 31522258
197 + 31522061 = 31522258
239 + 31522019 = 31522258
281 + 31521977 = 31522258
587 + 31521671 = 31522258

Showing the first eight; more decompositions exist.
