Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573148, here are decompositions:

37 + 31573111 = 31573148
127 + 31573021 = 31573148
199 + 31572949 = 31573148
307 + 31572841 = 31573148
379 + 31572769 = 31573148
421 + 31572727 = 31573148
499 + 31572649 = 31573148
577 + 31572571 = 31573148

Showing the first eight; more decompositions exist.
