Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612418, here are decompositions:

37 + 31612381 = 31612418
67 + 31612351 = 31612418
109 + 31612309 = 31612418
337 + 31612081 = 31612418
349 + 31612069 = 31612418
421 + 31611997 = 31612418
577 + 31611841 = 31612418
601 + 31611817 = 31612418

Showing the first eight; more decompositions exist.
