Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476886, here are decompositions:

5 + 31476881 = 31476886
263 + 31476623 = 31476886
293 + 31476593 = 31476886
449 + 31476437 = 31476886
503 + 31476383 = 31476886
569 + 31476317 = 31476886
647 + 31476239 = 31476886
743 + 31476143 = 31476886

Showing the first eight; more decompositions exist.
