Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469264, here are decompositions:

67 + 31469197 = 31469264
163 + 31469101 = 31469264
223 + 31469041 = 31469264
271 + 31468993 = 31469264
487 + 31468777 = 31469264
691 + 31468573 = 31469264
811 + 31468453 = 31469264
1021 + 31468243 = 31469264

Showing the first eight; more decompositions exist.
