Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465666, here are decompositions:

3 + 31465663 = 31465666
5 + 31465661 = 31465666
17 + 31465649 = 31465666
47 + 31465619 = 31465666
137 + 31465529 = 31465666
443 + 31465223 = 31465666
719 + 31464947 = 31465666
839 + 31464827 = 31465666

Showing the first eight; more decompositions exist.
