Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611924, here are decompositions:

7 + 31611917 = 31611924
13 + 31611911 = 31611924
17 + 31611907 = 31611924
31 + 31611893 = 31611924
41 + 31611883 = 31611924
73 + 31611851 = 31611924
83 + 31611841 = 31611924
107 + 31611817 = 31611924

Showing the first eight; more decompositions exist.
