Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513704, here are decompositions:

7 + 31513697 = 31513704
11 + 31513693 = 31513704
37 + 31513667 = 31513704
43 + 31513661 = 31513704
83 + 31513621 = 31513704
97 + 31513607 = 31513704
281 + 31513423 = 31513704
293 + 31513411 = 31513704

Showing the first eight; more decompositions exist.
