Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513096, here are decompositions:

5 + 31513091 = 31513096
23 + 31513073 = 31513096
47 + 31513049 = 31513096
59 + 31513037 = 31513096
89 + 31513007 = 31513096
137 + 31512959 = 31513096
149 + 31512947 = 31513096
227 + 31512869 = 31513096

Showing the first eight; more decompositions exist.
