Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626772, here are decompositions:

5 + 31626767 = 31626772
83 + 31626689 = 31626772
239 + 31626533 = 31626772
311 + 31626461 = 31626772
383 + 31626389 = 31626772
389 + 31626383 = 31626772
449 + 31626323 = 31626772
563 + 31626209 = 31626772

Showing the first eight; more decompositions exist.
