Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611644, here are decompositions:

3 + 31611641 = 31611644
37 + 31611607 = 31611644
61 + 31611583 = 31611644
67 + 31611577 = 31611644
157 + 31611487 = 31611644
241 + 31611403 = 31611644
277 + 31611367 = 31611644
373 + 31611271 = 31611644

Showing the first eight; more decompositions exist.
