Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103158, here are decompositions:

17 + 103141 = 103158
59 + 103099 = 103158
67 + 103091 = 103158
71 + 103087 = 103158
79 + 103079 = 103158
89 + 103069 = 103158
109 + 103049 = 103158
151 + 103007 = 103158

Showing the first eight; more decompositions exist.
