Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611966, here are decompositions:

59 + 31611907 = 31611966
73 + 31611893 = 31611966
83 + 31611883 = 31611966
97 + 31611869 = 31611966
137 + 31611829 = 31611966
149 + 31611817 = 31611966
163 + 31611803 = 31611966
229 + 31611737 = 31611966

Showing the first eight; more decompositions exist.
