Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469312, here are decompositions:

13 + 31469299 = 31469312
19 + 31469293 = 31469312
73 + 31469239 = 31469312
103 + 31469209 = 31469312
181 + 31469131 = 31469312
211 + 31469101 = 31469312
271 + 31469041 = 31469312
349 + 31468963 = 31469312

Showing the first eight; more decompositions exist.
