Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611982, here are decompositions:

41 + 31611941 = 31611982
71 + 31611911 = 31611982
89 + 31611893 = 31611982
113 + 31611869 = 31611982
131 + 31611851 = 31611982
179 + 31611803 = 31611982
263 + 31611719 = 31611982
401 + 31611581 = 31611982

Showing the first eight; more decompositions exist.
