Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573112, here are decompositions:

3 + 31573109 = 31573112
19 + 31573093 = 31573112
163 + 31572949 = 31573112
211 + 31572901 = 31573112
271 + 31572841 = 31573112
349 + 31572763 = 31573112
379 + 31572733 = 31573112
463 + 31572649 = 31573112

Showing the first eight; more decompositions exist.
