Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573010, here are decompositions:

3 + 31573007 = 31573010
31 + 31572979 = 31573010
61 + 31572949 = 31573010
67 + 31572943 = 31573010
109 + 31572901 = 31573010
241 + 31572769 = 31573010
277 + 31572733 = 31573010
283 + 31572727 = 31573010

Showing the first eight; more decompositions exist.
