Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606822, here are decompositions:

11 + 31606811 = 31606822
131 + 31606691 = 31606822
179 + 31606643 = 31606822
239 + 31606583 = 31606822
263 + 31606559 = 31606822
281 + 31606541 = 31606822
293 + 31606529 = 31606822
353 + 31606469 = 31606822

Showing the first eight; more decompositions exist.
