Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469162, here are decompositions:

19 + 31469143 = 31469162
31 + 31469131 = 31469162
61 + 31469101 = 31469162
199 + 31468963 = 31469162
313 + 31468849 = 31469162
463 + 31468699 = 31469162
619 + 31468543 = 31469162
691 + 31468471 = 31469162

Showing the first eight; more decompositions exist.
