Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611894, here are decompositions:

11 + 31611883 = 31611894
43 + 31611851 = 31611894
53 + 31611841 = 31611894
137 + 31611757 = 31611894
157 + 31611737 = 31611894
191 + 31611703 = 31611894
227 + 31611667 = 31611894
277 + 31611617 = 31611894

Showing the first eight; more decompositions exist.
