Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522332, here are decompositions:

5 + 31522327 = 31522332
19 + 31522313 = 31522332
89 + 31522243 = 31522332
103 + 31522229 = 31522332
113 + 31522219 = 31522332
151 + 31522181 = 31522332
229 + 31522103 = 31522332
241 + 31522091 = 31522332

Showing the first eight; more decompositions exist.
