Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613076, here are decompositions:

23 + 31613053 = 31613076
107 + 31612969 = 31613076
137 + 31612939 = 31613076
163 + 31612913 = 31613076
223 + 31612853 = 31613076
317 + 31612759 = 31613076
337 + 31612739 = 31613076
347 + 31612729 = 31613076

Showing the first eight; more decompositions exist.
