Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501926, here are decompositions:

13 + 31501913 = 31501926
19 + 31501907 = 31501926
47 + 31501879 = 31501926
103 + 31501823 = 31501926
107 + 31501819 = 31501926
167 + 31501759 = 31501926
199 + 31501727 = 31501926
227 + 31501699 = 31501926

Showing the first eight; more decompositions exist.
