Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611622, here are decompositions:

5 + 31611617 = 31611622
41 + 31611581 = 31611622
83 + 31611539 = 31611622
113 + 31611509 = 31611622
149 + 31611473 = 31611622
281 + 31611341 = 31611622
293 + 31611329 = 31611622
311 + 31611311 = 31611622

Showing the first eight; more decompositions exist.
