Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612194, here are decompositions:

43 + 31612151 = 31612194
73 + 31612121 = 31612194
113 + 31612081 = 31612194
151 + 31612043 = 31612194
181 + 31612013 = 31612194
197 + 31611997 = 31612194
277 + 31611917 = 31612194
283 + 31611911 = 31612194

Showing the first eight; more decompositions exist.
