Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613716, here are decompositions:

47 + 31613669 = 31613716
89 + 31613627 = 31613716
137 + 31613579 = 31613716
317 + 31613399 = 31613716
359 + 31613357 = 31613716
383 + 31613333 = 31613716
467 + 31613249 = 31613716
599 + 31613117 = 31613716

Showing the first eight; more decompositions exist.
