Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626736, here are decompositions:

47 + 31626689 = 31626736
173 + 31626563 = 31626736
179 + 31626557 = 31626736
347 + 31626389 = 31626736
353 + 31626383 = 31626736
359 + 31626377 = 31626736
503 + 31626233 = 31626736
569 + 31626167 = 31626736

Showing the first eight; more decompositions exist.
