Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519846, here are decompositions:

3 + 31519843 = 31519846
23 + 31519823 = 31519846
53 + 31519793 = 31519846
167 + 31519679 = 31519846
173 + 31519673 = 31519846
263 + 31519583 = 31519846
359 + 31519487 = 31519846
383 + 31519463 = 31519846

Showing the first eight; more decompositions exist.
