Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613404, here are decompositions:

3 + 31613401 = 31613404
5 + 31613399 = 31613404
47 + 31613357 = 31613404
71 + 31613333 = 31613404
113 + 31613291 = 31613404
233 + 31613171 = 31613404
443 + 31612961 = 31613404
491 + 31612913 = 31613404

Showing the first eight; more decompositions exist.
