Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612244, here are decompositions:

3 + 31612241 = 31612244
43 + 31612201 = 31612244
163 + 31612081 = 31612244
337 + 31611907 = 31612244
487 + 31611757 = 31612244
541 + 31611703 = 31612244
571 + 31611673 = 31612244
577 + 31611667 = 31612244

Showing the first eight; more decompositions exist.
