Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522458, here are decompositions:

7 + 31522451 = 31522458
17 + 31522441 = 31522458
47 + 31522411 = 31522458
101 + 31522357 = 31522458
127 + 31522331 = 31522458
131 + 31522327 = 31522458
181 + 31522277 = 31522458
211 + 31522247 = 31522458

Showing the first eight; more decompositions exist.
