Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469196, here are decompositions:

19 + 31469177 = 31469196
53 + 31469143 = 31469196
127 + 31469069 = 31469196
163 + 31469033 = 31469196
229 + 31468967 = 31469196
233 + 31468963 = 31469196
277 + 31468919 = 31469196
293 + 31468903 = 31469196

Showing the first eight; more decompositions exist.
