Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573122, here are decompositions:

11 + 31573111 = 31573122
13 + 31573109 = 31573122
19 + 31573103 = 31573122
29 + 31573093 = 31573122
101 + 31573021 = 31573122
151 + 31572971 = 31573122
173 + 31572949 = 31573122
179 + 31572943 = 31573122

Showing the first eight; more decompositions exist.
