Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613102, here are decompositions:

151 + 31612951 = 31613102
163 + 31612939 = 31613102
211 + 31612891 = 31613102
229 + 31612873 = 31613102
271 + 31612831 = 31613102
349 + 31612753 = 31613102
373 + 31612729 = 31613102
439 + 31612663 = 31613102

Showing the first eight; more decompositions exist.
