Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573822, here are decompositions:

3 + 31573819 = 31573822
29 + 31573793 = 31573822
179 + 31573643 = 31573822
239 + 31573583 = 31573822
251 + 31573571 = 31573822
263 + 31573559 = 31573822
359 + 31573463 = 31573822
431 + 31573391 = 31573822

Showing the first eight; more decompositions exist.
