Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612902, here are decompositions:

11 + 31612891 = 31612902
29 + 31612873 = 31612902
71 + 31612831 = 31612902
149 + 31612753 = 31612902
163 + 31612739 = 31612902
173 + 31612729 = 31612902
239 + 31612663 = 31612902
241 + 31612661 = 31612902

Showing the first eight; more decompositions exist.
