Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469156, here are decompositions:

13 + 31469143 = 31469156
163 + 31468993 = 31469156
193 + 31468963 = 31469156
307 + 31468849 = 31469156
379 + 31468777 = 31469156
457 + 31468699 = 31469156
613 + 31468543 = 31469156
709 + 31468447 = 31469156

Showing the first eight; more decompositions exist.
