Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470086, here are decompositions:

13 + 31470073 = 31470086
19 + 31470067 = 31470086
73 + 31470013 = 31470086
97 + 31469989 = 31470086
163 + 31469923 = 31470086
229 + 31469857 = 31470086
397 + 31469689 = 31470086
433 + 31469653 = 31470086

Showing the first eight; more decompositions exist.
