Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470008, here are decompositions:

19 + 31469989 = 31470008
151 + 31469857 = 31470008
211 + 31469797 = 31470008
277 + 31469731 = 31470008
337 + 31469671 = 31470008
379 + 31469629 = 31470008
421 + 31469587 = 31470008
439 + 31469569 = 31470008

Showing the first eight; more decompositions exist.
