Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610934, here are decompositions:

23 + 31610911 = 31610934
41 + 31610893 = 31610934
67 + 31610867 = 31610934
163 + 31610771 = 31610934
193 + 31610741 = 31610934
211 + 31610723 = 31610934
227 + 31610707 = 31610934
293 + 31610641 = 31610934

Showing the first eight; more decompositions exist.
