Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612922, here are decompositions:

31 + 31612891 = 31612922
163 + 31612759 = 31612922
193 + 31612729 = 31612922
349 + 31612573 = 31612922
409 + 31612513 = 31612922
499 + 31612423 = 31612922
541 + 31612381 = 31612922
571 + 31612351 = 31612922

Showing the first eight; more decompositions exist.
