Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465498, here are decompositions:

17 + 31465481 = 31465498
47 + 31465451 = 31465498
107 + 31465391 = 31465498
557 + 31464941 = 31465498
677 + 31464821 = 31465498
797 + 31464701 = 31465498
881 + 31464617 = 31465498
941 + 31464557 = 31465498

Showing the first eight; more decompositions exist.
