Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522454, here are decompositions:

3 + 31522451 = 31522454
13 + 31522441 = 31522454
43 + 31522411 = 31522454
97 + 31522357 = 31522454
127 + 31522327 = 31522454
157 + 31522297 = 31522454
211 + 31522243 = 31522454
433 + 31522021 = 31522454

Showing the first eight; more decompositions exist.
