Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573226, here are decompositions:

37 + 31573189 = 31573226
73 + 31573153 = 31573226
103 + 31573123 = 31573226
199 + 31573027 = 31573226
277 + 31572949 = 31573226
283 + 31572943 = 31573226
457 + 31572769 = 31573226
463 + 31572763 = 31573226

Showing the first eight; more decompositions exist.
