Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470392, here are decompositions:

13 + 31470379 = 31470392
193 + 31470199 = 31470392
199 + 31470193 = 31470392
241 + 31470151 = 31470392
379 + 31470013 = 31470392
439 + 31469953 = 31470392
631 + 31469761 = 31470392
661 + 31469731 = 31470392

Showing the first eight; more decompositions exist.
