Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470068, here are decompositions:

31 + 31470037 = 31470068
79 + 31469989 = 31470068
211 + 31469857 = 31470068
271 + 31469797 = 31470068
307 + 31469761 = 31470068
337 + 31469731 = 31470068
379 + 31469689 = 31470068
397 + 31469671 = 31470068

Showing the first eight; more decompositions exist.
