Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470076, here are decompositions:

3 + 31470073 = 31470076
89 + 31469987 = 31470076
173 + 31469903 = 31470076
227 + 31469849 = 31470076
263 + 31469813 = 31470076
293 + 31469783 = 31470076
353 + 31469723 = 31470076
557 + 31469519 = 31470076

Showing the first eight; more decompositions exist.
