Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470662, here are decompositions:

43 + 31470619 = 31470662
193 + 31470469 = 31470662
283 + 31470379 = 31470662
439 + 31470223 = 31470662
463 + 31470199 = 31470662
673 + 31469989 = 31470662
709 + 31469953 = 31470662
739 + 31469923 = 31470662

Showing the first eight; more decompositions exist.
