Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469016, here are decompositions:

23 + 31468993 = 31469016
53 + 31468963 = 31469016
97 + 31468919 = 31469016
113 + 31468903 = 31469016
167 + 31468849 = 31469016
193 + 31468823 = 31469016
223 + 31468793 = 31469016
239 + 31468777 = 31469016

Showing the first eight; more decompositions exist.
