Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612006, here are decompositions:

89 + 31611917 = 31612006
113 + 31611893 = 31612006
137 + 31611869 = 31612006
269 + 31611737 = 31612006
347 + 31611659 = 31612006
359 + 31611647 = 31612006
389 + 31611617 = 31612006
467 + 31611539 = 31612006

Showing the first eight; more decompositions exist.
