Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611984, here are decompositions:

43 + 31611941 = 31611984
67 + 31611917 = 31611984
73 + 31611911 = 31611984
101 + 31611883 = 31611984
167 + 31611817 = 31611984
181 + 31611803 = 31611984
223 + 31611761 = 31611984
227 + 31611757 = 31611984

Showing the first eight; more decompositions exist.
