Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611422, here are decompositions:

19 + 31611403 = 31611422
43 + 31611379 = 31611422
103 + 31611319 = 31611422
151 + 31611271 = 31611422
373 + 31611049 = 31611422
379 + 31611043 = 31611422
631 + 31610791 = 31611422
643 + 31610779 = 31611422

Showing the first eight; more decompositions exist.
