Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31086, here are decompositions:

5 + 31081 = 31086
7 + 31079 = 31086
17 + 31069 = 31086
23 + 31063 = 31086
47 + 31039 = 31086
53 + 31033 = 31086
67 + 31019 = 31086
73 + 31013 = 31086

Showing the first eight; more decompositions exist.
