Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626892, here are decompositions:

23 + 31626869 = 31626892
53 + 31626839 = 31626892
359 + 31626533 = 31626892
431 + 31626461 = 31626892
503 + 31626389 = 31626892
509 + 31626383 = 31626892
569 + 31626323 = 31626892
659 + 31626233 = 31626892

Showing the first eight; more decompositions exist.
