Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611350, here are decompositions:

31 + 31611319 = 31611350
79 + 31611271 = 31611350
163 + 31611187 = 31611350
223 + 31611127 = 31611350
283 + 31611067 = 31611350
307 + 31611043 = 31611350
313 + 31611037 = 31611350
439 + 31610911 = 31611350

Showing the first eight; more decompositions exist.
