Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612718, here are decompositions:

97 + 31612621 = 31612718
337 + 31612381 = 31612718
349 + 31612369 = 31612718
367 + 31612351 = 31612718
409 + 31612309 = 31612718
811 + 31611907 = 31612718
877 + 31611841 = 31612718
1009 + 31611709 = 31612718

Showing the first eight; more decompositions exist.
