Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460760, here are decompositions:

17 + 31460743 = 31460760
31 + 31460729 = 31460760
43 + 31460717 = 31460760
59 + 31460701 = 31460760
83 + 31460677 = 31460760
103 + 31460657 = 31460760
113 + 31460647 = 31460760
151 + 31460609 = 31460760

Showing the first eight; more decompositions exist.
