Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522866, here are decompositions:

19 + 31522847 = 31522866
43 + 31522823 = 31522866
149 + 31522717 = 31522866
173 + 31522693 = 31522866
197 + 31522669 = 31522866
233 + 31522633 = 31522866
269 + 31522597 = 31522866
283 + 31522583 = 31522866

Showing the first eight; more decompositions exist.
