Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611908, here are decompositions:

67 + 31611841 = 31611908
79 + 31611829 = 31611908
151 + 31611757 = 31611908
199 + 31611709 = 31611908
241 + 31611667 = 31611908
331 + 31611577 = 31611908
421 + 31611487 = 31611908
541 + 31611367 = 31611908

Showing the first eight; more decompositions exist.
