Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611470, here are decompositions:

3 + 31611467 = 31611470
13 + 31611457 = 31611470
31 + 31611439 = 31611470
67 + 31611403 = 31611470
103 + 31611367 = 31611470
151 + 31611319 = 31611470
199 + 31611271 = 31611470
283 + 31611187 = 31611470

Showing the first eight; more decompositions exist.
