Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573110, here are decompositions:

7 + 31573103 = 31573110
17 + 31573093 = 31573110
53 + 31573057 = 31573110
73 + 31573037 = 31573110
83 + 31573027 = 31573110
89 + 31573021 = 31573110
103 + 31573007 = 31573110
131 + 31572979 = 31573110

Showing the first eight; more decompositions exist.
