Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612930, here are decompositions:

17 + 31612913 = 31612930
191 + 31612739 = 31612930
197 + 31612733 = 31612930
263 + 31612667 = 31612930
269 + 31612661 = 31612930
311 + 31612619 = 31612930
347 + 31612583 = 31612930
383 + 31612547 = 31612930

Showing the first eight; more decompositions exist.
