Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522666, here are decompositions:

3 + 31522663 = 31522666
53 + 31522613 = 31522666
83 + 31522583 = 31522666
113 + 31522553 = 31522666
137 + 31522529 = 31522666
173 + 31522493 = 31522666
233 + 31522433 = 31522666
293 + 31522373 = 31522666

Showing the first eight; more decompositions exist.
