Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469916, here are decompositions:

13 + 31469903 = 31469916
59 + 31469857 = 31469916
67 + 31469849 = 31469916
103 + 31469813 = 31469916
193 + 31469723 = 31469916
227 + 31469689 = 31469916
263 + 31469653 = 31469916
293 + 31469623 = 31469916

Showing the first eight; more decompositions exist.
