Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611614, here are decompositions:

7 + 31611607 = 31611614
31 + 31611583 = 31611614
37 + 31611577 = 31611614
61 + 31611553 = 31611614
127 + 31611487 = 31611614
157 + 31611457 = 31611614
211 + 31611403 = 31611614
313 + 31611301 = 31611614

Showing the first eight; more decompositions exist.
