Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469930, here are decompositions:

7 + 31469923 = 31469930
73 + 31469857 = 31469930
199 + 31469731 = 31469930
241 + 31469689 = 31469930
277 + 31469653 = 31469930
307 + 31469623 = 31469930
367 + 31469563 = 31469930
463 + 31469467 = 31469930

Showing the first eight; more decompositions exist.
