Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470046, here are decompositions:

59 + 31469987 = 31470046
197 + 31469849 = 31470046
233 + 31469813 = 31470046
263 + 31469783 = 31470046
467 + 31469579 = 31470046
599 + 31469447 = 31470046
659 + 31469387 = 31470046
719 + 31469327 = 31470046

Showing the first eight; more decompositions exist.
