Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465204, here are decompositions:

11 + 31465193 = 31465204
257 + 31464947 = 31465204
263 + 31464941 = 31465204
383 + 31464821 = 31465204
503 + 31464701 = 31465204
587 + 31464617 = 31465204
647 + 31464557 = 31465204
761 + 31464443 = 31465204

Showing the first eight; more decompositions exist.
