Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611922, here are decompositions:

5 + 31611917 = 31611922
11 + 31611911 = 31611922
29 + 31611893 = 31611922
53 + 31611869 = 31611922
71 + 31611851 = 31611922
263 + 31611659 = 31611922
281 + 31611641 = 31611922
383 + 31611539 = 31611922

Showing the first eight; more decompositions exist.
