Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611464, here are decompositions:

7 + 31611457 = 31611464
61 + 31611403 = 31611464
97 + 31611367 = 31611464
163 + 31611301 = 31611464
193 + 31611271 = 31611464
277 + 31611187 = 31611464
337 + 31611127 = 31611464
397 + 31611067 = 31611464

Showing the first eight; more decompositions exist.
