Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519692, here are decompositions:

5 + 31519687 = 31519692
13 + 31519679 = 31519692
19 + 31519673 = 31519692
31 + 31519661 = 31519692
109 + 31519583 = 31519692
173 + 31519519 = 31519692
229 + 31519463 = 31519692
233 + 31519459 = 31519692

Showing the first eight; more decompositions exist.
