Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626922, here are decompositions:

23 + 31626899 = 31626922
29 + 31626893 = 31626922
53 + 31626869 = 31626922
83 + 31626839 = 31626922
233 + 31626689 = 31626922
359 + 31626563 = 31626922
389 + 31626533 = 31626922
461 + 31626461 = 31626922

Showing the first eight; more decompositions exist.
