Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469864, here are decompositions:

3 + 31469861 = 31469864
7 + 31469857 = 31469864
67 + 31469797 = 31469864
103 + 31469761 = 31469864
193 + 31469671 = 31469864
211 + 31469653 = 31469864
241 + 31469623 = 31469864
277 + 31469587 = 31469864

Showing the first eight; more decompositions exist.
