Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469252, here are decompositions:

13 + 31469239 = 31469252
43 + 31469209 = 31469252
109 + 31469143 = 31469252
151 + 31469101 = 31469252
211 + 31469041 = 31469252
349 + 31468903 = 31469252
709 + 31468543 = 31469252
853 + 31468399 = 31469252

Showing the first eight; more decompositions exist.
