Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469192, here are decompositions:

61 + 31469131 = 31469192
151 + 31469041 = 31469192
199 + 31468993 = 31469192
229 + 31468963 = 31469192
331 + 31468861 = 31469192
619 + 31468573 = 31469192
739 + 31468453 = 31469192
823 + 31468369 = 31469192

Showing the first eight; more decompositions exist.
