Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522690, here are decompositions:

107 + 31522583 = 31522690
137 + 31522553 = 31522690
149 + 31522541 = 31522690
167 + 31522523 = 31522690
197 + 31522493 = 31522690
239 + 31522451 = 31522690
257 + 31522433 = 31522690
317 + 31522373 = 31522690

Showing the first eight; more decompositions exist.
