Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470284, here are decompositions:

61 + 31470223 = 31470284
67 + 31470217 = 31470284
211 + 31470073 = 31470284
271 + 31470013 = 31470284
331 + 31469953 = 31470284
487 + 31469797 = 31470284
523 + 31469761 = 31470284
613 + 31469671 = 31470284

Showing the first eight; more decompositions exist.
