Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31082, here are decompositions:

3 + 31079 = 31082
13 + 31069 = 31082
19 + 31063 = 31082
31 + 31051 = 31082
43 + 31039 = 31082
151 + 30931 = 31082
211 + 30871 = 31082
223 + 30859 = 31082

Showing the first eight; more decompositions exist.
