Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103178, here are decompositions:

7 + 103171 = 103178
37 + 103141 = 103178
79 + 103099 = 103178
109 + 103069 = 103178
211 + 102967 = 103178
307 + 102871 = 103178
337 + 102841 = 103178
349 + 102829 = 103178

Showing the first eight; more decompositions exist.
