Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612694, here are decompositions:

31 + 31612663 = 31612694
67 + 31612627 = 31612694
73 + 31612621 = 31612694
97 + 31612597 = 31612694
163 + 31612531 = 31612694
181 + 31612513 = 31612694
241 + 31612453 = 31612694
271 + 31612423 = 31612694

Showing the first eight; more decompositions exist.
