Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522318, here are decompositions:

5 + 31522313 = 31522318
41 + 31522277 = 31522318
71 + 31522247 = 31522318
89 + 31522229 = 31522318
137 + 31522181 = 31522318
227 + 31522091 = 31522318
257 + 31522061 = 31522318
431 + 31521887 = 31522318

Showing the first eight; more decompositions exist.
