Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103140, here are decompositions:

17 + 103123 = 103140
41 + 103099 = 103140
47 + 103093 = 103140
53 + 103087 = 103140
61 + 103079 = 103140
71 + 103069 = 103140
73 + 103067 = 103140
97 + 103043 = 103140

Showing the first eight; more decompositions exist.
