Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522546, here are decompositions:

5 + 31522541 = 31522546
17 + 31522529 = 31522546
23 + 31522523 = 31522546
53 + 31522493 = 31522546
113 + 31522433 = 31522546
173 + 31522373 = 31522546
233 + 31522313 = 31522546
269 + 31522277 = 31522546

Showing the first eight; more decompositions exist.
