Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465692, here are decompositions:

19 + 31465673 = 31465692
29 + 31465663 = 31465692
31 + 31465661 = 31465692
43 + 31465649 = 31465692
61 + 31465631 = 31465692
73 + 31465619 = 31465692
113 + 31465579 = 31465692
131 + 31465561 = 31465692

Showing the first eight; more decompositions exist.
