Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486692, here are decompositions:

31 + 31486661 = 31486692
53 + 31486639 = 31486692
59 + 31486633 = 31486692
79 + 31486613 = 31486692
89 + 31486603 = 31486692
163 + 31486529 = 31486692
199 + 31486493 = 31486692
229 + 31486463 = 31486692

Showing the first eight; more decompositions exist.
