Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613662, here are decompositions:

23 + 31613639 = 31613662
83 + 31613579 = 31613662
149 + 31613513 = 31613662
251 + 31613411 = 31613662
263 + 31613399 = 31613662
419 + 31613243 = 31613662
491 + 31613171 = 31613662
701 + 31612961 = 31613662

Showing the first eight; more decompositions exist.
