Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573190, here are decompositions:

37 + 31573153 = 31573190
67 + 31573123 = 31573190
79 + 31573111 = 31573190
97 + 31573093 = 31573190
163 + 31573027 = 31573190
211 + 31572979 = 31573190
241 + 31572949 = 31573190
349 + 31572841 = 31573190

Showing the first eight; more decompositions exist.
