Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573022, here are decompositions:

43 + 31572979 = 31573022
73 + 31572949 = 31573022
79 + 31572943 = 31573022
181 + 31572841 = 31573022
199 + 31572823 = 31573022
373 + 31572649 = 31573022
433 + 31572589 = 31573022
463 + 31572559 = 31573022

Showing the first eight; more decompositions exist.
