Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612400, here are decompositions:

19 + 31612381 = 31612400
31 + 31612369 = 31612400
37 + 31612363 = 31612400
199 + 31612201 = 31612400
331 + 31612069 = 31612400
571 + 31611829 = 31612400
643 + 31611757 = 31612400
691 + 31611709 = 31612400

Showing the first eight; more decompositions exist.
