Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465662, here are decompositions:

13 + 31465649 = 31465662
31 + 31465631 = 31465662
43 + 31465619 = 31465662
61 + 31465601 = 31465662
83 + 31465579 = 31465662
101 + 31465561 = 31465662
181 + 31465481 = 31465662
211 + 31465451 = 31465662

Showing the first eight; more decompositions exist.
