Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611912, here are decompositions:

5 + 31611907 = 31611912
19 + 31611893 = 31611912
29 + 31611883 = 31611912
43 + 31611869 = 31611912
61 + 31611851 = 31611912
71 + 31611841 = 31611912
83 + 31611829 = 31611912
109 + 31611803 = 31611912

Showing the first eight; more decompositions exist.
