Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31116, here are decompositions:

37 + 31079 = 31116
47 + 31069 = 31116
53 + 31063 = 31116
83 + 31033 = 31116
97 + 31019 = 31116
103 + 31013 = 31116
139 + 30977 = 31116
167 + 30949 = 31116

Showing the first eight; more decompositions exist.
