Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612136, here are decompositions:

67 + 31612069 = 31612136
139 + 31611997 = 31612136
229 + 31611907 = 31612136
307 + 31611829 = 31612136
379 + 31611757 = 31612136
433 + 31611703 = 31612136
463 + 31611673 = 31612136
733 + 31611403 = 31612136

Showing the first eight; more decompositions exist.
