Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522534, here are decompositions:

5 + 31522529 = 31522534
11 + 31522523 = 31522534
41 + 31522493 = 31522534
83 + 31522451 = 31522534
101 + 31522433 = 31522534
257 + 31522277 = 31522534
293 + 31522241 = 31522534
353 + 31522181 = 31522534

Showing the first eight; more decompositions exist.
