Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103154, here are decompositions:

13 + 103141 = 103154
31 + 103123 = 103154
61 + 103093 = 103154
67 + 103087 = 103154
223 + 102931 = 103154
241 + 102913 = 103154
277 + 102877 = 103154
283 + 102871 = 103154

Showing the first eight; more decompositions exist.
