Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613700, here are decompositions:

31 + 31613669 = 31613700
61 + 31613639 = 31613700
71 + 31613629 = 31613700
73 + 31613627 = 31613700
149 + 31613551 = 31613700
263 + 31613437 = 31613700
317 + 31613383 = 31613700
359 + 31613341 = 31613700

Showing the first eight; more decompositions exist.
