Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513114, here are decompositions:

23 + 31513091 = 31513114
41 + 31513073 = 31513114
107 + 31513007 = 31513114
167 + 31512947 = 31513114
383 + 31512731 = 31513114
431 + 31512683 = 31513114
557 + 31512557 = 31513114
593 + 31512521 = 31513114

Showing the first eight; more decompositions exist.
