Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103170, here are decompositions:

29 + 103141 = 103170
47 + 103123 = 103170
71 + 103099 = 103170
79 + 103091 = 103170
83 + 103087 = 103170
101 + 103069 = 103170
103 + 103067 = 103170
127 + 103043 = 103170

Showing the first eight; more decompositions exist.
