Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464892, here are decompositions:

71 + 31464821 = 31464892
83 + 31464809 = 31464892
191 + 31464701 = 31464892
311 + 31464581 = 31464892
383 + 31464509 = 31464892
449 + 31464443 = 31464892
491 + 31464401 = 31464892
659 + 31464233 = 31464892

Showing the first eight; more decompositions exist.
