Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469204, here are decompositions:

7 + 31469197 = 31469204
61 + 31469143 = 31469204
73 + 31469131 = 31469204
103 + 31469101 = 31469204
163 + 31469041 = 31469204
211 + 31468993 = 31469204
241 + 31468963 = 31469204
607 + 31468597 = 31469204

Showing the first eight; more decompositions exist.
