Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612310, here are decompositions:

3 + 31612307 = 31612310
109 + 31612201 = 31612310
229 + 31612081 = 31612310
241 + 31612069 = 31612310
313 + 31611997 = 31612310
577 + 31611733 = 31612310
601 + 31611709 = 31612310
607 + 31611703 = 31612310

Showing the first eight; more decompositions exist.
