Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626706, here are decompositions:

17 + 31626689 = 31626706
149 + 31626557 = 31626706
173 + 31626533 = 31626706
269 + 31626437 = 31626706
317 + 31626389 = 31626706
347 + 31626359 = 31626706
383 + 31626323 = 31626706
509 + 31626197 = 31626706

Showing the first eight; more decompositions exist.
