Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476826, here are decompositions:

5 + 31476821 = 31476826
83 + 31476743 = 31476826
233 + 31476593 = 31476826
239 + 31476587 = 31476826
317 + 31476509 = 31476826
389 + 31476437 = 31476826
443 + 31476383 = 31476826
509 + 31476317 = 31476826

Showing the first eight; more decompositions exist.
