Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465354, here are decompositions:

131 + 31465223 = 31465354
293 + 31465061 = 31465354
653 + 31464701 = 31465354
773 + 31464581 = 31465354
797 + 31464557 = 31465354
911 + 31464443 = 31465354
953 + 31464401 = 31465354
1013 + 31464341 = 31465354

Showing the first eight; more decompositions exist.
