Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470074, here are decompositions:

7 + 31470067 = 31470074
37 + 31470037 = 31470074
61 + 31470013 = 31470074
151 + 31469923 = 31470074
277 + 31469797 = 31470074
313 + 31469761 = 31470074
421 + 31469653 = 31470074
487 + 31469587 = 31470074

Showing the first eight; more decompositions exist.
