Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522966, here are decompositions:

5 + 31522961 = 31522966
29 + 31522937 = 31522966
353 + 31522613 = 31522966
383 + 31522583 = 31522966
443 + 31522523 = 31522966
593 + 31522373 = 31522966
653 + 31522313 = 31522966
719 + 31522247 = 31522966

Showing the first eight; more decompositions exist.
