Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611734, here are decompositions:

31 + 31611703 = 31611734
61 + 31611673 = 31611734
67 + 31611667 = 31611734
127 + 31611607 = 31611734
151 + 31611583 = 31611734
157 + 31611577 = 31611734
181 + 31611553 = 31611734
277 + 31611457 = 31611734

Showing the first eight; more decompositions exist.
