Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612622, here are decompositions:

3 + 31612619 = 31612622
109 + 31612513 = 31612622
193 + 31612429 = 31612622
199 + 31612423 = 31612622
241 + 31612381 = 31612622
271 + 31612351 = 31612622
313 + 31612309 = 31612622
421 + 31612201 = 31612622

Showing the first eight; more decompositions exist.
