Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573074, here are decompositions:

17 + 31573057 = 31573074
37 + 31573037 = 31573074
47 + 31573027 = 31573074
53 + 31573021 = 31573074
67 + 31573007 = 31573074
103 + 31572971 = 31573074
131 + 31572943 = 31573074
173 + 31572901 = 31573074

Showing the first eight; more decompositions exist.
