Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612706, here are decompositions:

43 + 31612663 = 31612706
79 + 31612627 = 31612706
109 + 31612597 = 31612706
193 + 31612513 = 31612706
277 + 31612429 = 31612706
283 + 31612423 = 31612706
337 + 31612369 = 31612706
397 + 31612309 = 31612706

Showing the first eight; more decompositions exist.
