Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513926, here are decompositions:

47 + 31513879 = 31513926
53 + 31513873 = 31513926
83 + 31513843 = 31513926
107 + 31513819 = 31513926
109 + 31513817 = 31513926
139 + 31513787 = 31513926
229 + 31513697 = 31513926
233 + 31513693 = 31513926

Showing the first eight; more decompositions exist.
