Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626730, here are decompositions:

41 + 31626689 = 31626730
167 + 31626563 = 31626730
173 + 31626557 = 31626730
197 + 31626533 = 31626730
269 + 31626461 = 31626730
293 + 31626437 = 31626730
347 + 31626383 = 31626730
353 + 31626377 = 31626730

Showing the first eight; more decompositions exist.
