Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103128, here are decompositions:

5 + 103123 = 103128
29 + 103099 = 103128
37 + 103091 = 103128
41 + 103087 = 103128
59 + 103069 = 103128
61 + 103067 = 103128
79 + 103049 = 103128
127 + 103001 = 103128

Showing the first eight; more decompositions exist.
