Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469294, here are decompositions:

7 + 31469287 = 31469294
97 + 31469197 = 31469294
151 + 31469143 = 31469294
163 + 31469131 = 31469294
193 + 31469101 = 31469294
331 + 31468963 = 31469294
433 + 31468861 = 31469294
751 + 31468543 = 31469294

Showing the first eight; more decompositions exist.
