Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612544, here are decompositions:

13 + 31612531 = 31612544
31 + 31612513 = 31612544
163 + 31612381 = 31612544
181 + 31612363 = 31612544
193 + 31612351 = 31612544
463 + 31612081 = 31612544
547 + 31611997 = 31612544
661 + 31611883 = 31612544

Showing the first eight; more decompositions exist.
