Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103130, here are decompositions:

7 + 103123 = 103130
31 + 103099 = 103130
37 + 103093 = 103130
43 + 103087 = 103130
61 + 103069 = 103130
163 + 102967 = 103130
199 + 102931 = 103130
271 + 102859 = 103130

Showing the first eight; more decompositions exist.
