Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522422, here are decompositions:

11 + 31522411 = 31522422
59 + 31522363 = 31522422
83 + 31522339 = 31522422
109 + 31522313 = 31522422
179 + 31522243 = 31522422
181 + 31522241 = 31522422
193 + 31522229 = 31522422
241 + 31522181 = 31522422

Showing the first eight; more decompositions exist.
