Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606766, here are decompositions:

13 + 31606753 = 31606766
109 + 31606657 = 31606766
223 + 31606543 = 31606766
229 + 31606537 = 31606766
337 + 31606429 = 31606766
379 + 31606387 = 31606766
397 + 31606369 = 31606766
487 + 31606279 = 31606766

Showing the first eight; more decompositions exist.
