Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513054, here are decompositions:

5 + 31513049 = 31513054
17 + 31513037 = 31513054
47 + 31513007 = 31513054
107 + 31512947 = 31513054
227 + 31512827 = 31513054
467 + 31512587 = 31513054
863 + 31512191 = 31513054
941 + 31512113 = 31513054

Showing the first eight; more decompositions exist.
