Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611954, here are decompositions:

13 + 31611941 = 31611954
37 + 31611917 = 31611954
43 + 31611911 = 31611954
47 + 31611907 = 31611954
61 + 31611893 = 31611954
71 + 31611883 = 31611954
103 + 31611851 = 31611954
113 + 31611841 = 31611954

Showing the first eight; more decompositions exist.
