Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31136, here are decompositions:

13 + 31123 = 31136
67 + 31069 = 31136
73 + 31063 = 31136
97 + 31039 = 31136
103 + 31033 = 31136
199 + 30937 = 31136
277 + 30859 = 31136
283 + 30853 = 31136

Showing the first eight; more decompositions exist.
