Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513846, here are decompositions:

3 + 31513843 = 31513846
29 + 31513817 = 31513846
53 + 31513793 = 31513846
59 + 31513787 = 31513846
107 + 31513739 = 31513846
137 + 31513709 = 31513846
149 + 31513697 = 31513846
179 + 31513667 = 31513846

Showing the first eight; more decompositions exist.
