Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613386, here are decompositions:

3 + 31613383 = 31613386
29 + 31613357 = 31613386
53 + 31613333 = 31613386
137 + 31613249 = 31613386
269 + 31613117 = 31613386
359 + 31613027 = 31613386
647 + 31612739 = 31613386
653 + 31612733 = 31613386

Showing the first eight; more decompositions exist.
