Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573134, here are decompositions:

7 + 31573127 = 31573134
11 + 31573123 = 31573134
23 + 31573111 = 31573134
31 + 31573103 = 31573134
41 + 31573093 = 31573134
97 + 31573037 = 31573134
107 + 31573027 = 31573134
113 + 31573021 = 31573134

Showing the first eight; more decompositions exist.
