Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522354, here are decompositions:

23 + 31522331 = 31522354
41 + 31522313 = 31522354
107 + 31522247 = 31522354
113 + 31522241 = 31522354
173 + 31522181 = 31522354
251 + 31522103 = 31522354
263 + 31522091 = 31522354
293 + 31522061 = 31522354

Showing the first eight; more decompositions exist.
