Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522330, here are decompositions:

3 + 31522327 = 31522330
17 + 31522313 = 31522330
53 + 31522277 = 31522330
83 + 31522247 = 31522330
89 + 31522241 = 31522330
101 + 31522229 = 31522330
149 + 31522181 = 31522330
227 + 31522103 = 31522330

Showing the first eight; more decompositions exist.
