Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611964, here are decompositions:

23 + 31611941 = 31611964
47 + 31611917 = 31611964
53 + 31611911 = 31611964
71 + 31611893 = 31611964
113 + 31611851 = 31611964
227 + 31611737 = 31611964
317 + 31611647 = 31611964
347 + 31611617 = 31611964

Showing the first eight; more decompositions exist.
