Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513834, here are decompositions:

3 + 31513831 = 31513834
17 + 31513817 = 31513834
41 + 31513793 = 31513834
47 + 31513787 = 31513834
113 + 31513721 = 31513834
137 + 31513697 = 31513834
167 + 31513667 = 31513834
173 + 31513661 = 31513834

Showing the first eight; more decompositions exist.
