Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522240, here are decompositions:

11 + 31522229 = 31522240
59 + 31522181 = 31522240
137 + 31522103 = 31522240
149 + 31522091 = 31522240
179 + 31522061 = 31522240
227 + 31522013 = 31522240
263 + 31521977 = 31522240
353 + 31521887 = 31522240

Showing the first eight; more decompositions exist.
