Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613012, here are decompositions:

31 + 31612981 = 31613012
43 + 31612969 = 31613012
61 + 31612951 = 31613012
73 + 31612939 = 31613012
139 + 31612873 = 31613012
181 + 31612831 = 31613012
283 + 31612729 = 31613012
349 + 31612663 = 31613012

Showing the first eight; more decompositions exist.
