Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470368, here are decompositions:

31 + 31470337 = 31470368
109 + 31470259 = 31470368
151 + 31470217 = 31470368
271 + 31470097 = 31470368
331 + 31470037 = 31470368
379 + 31469989 = 31470368
571 + 31469797 = 31470368
607 + 31469761 = 31470368

Showing the first eight; more decompositions exist.
