Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626700, here are decompositions:

11 + 31626689 = 31626700
137 + 31626563 = 31626700
167 + 31626533 = 31626700
239 + 31626461 = 31626700
263 + 31626437 = 31626700
293 + 31626407 = 31626700
311 + 31626389 = 31626700
317 + 31626383 = 31626700

Showing the first eight; more decompositions exist.
