Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103238, here are decompositions:

7 + 103231 = 103238
61 + 103177 = 103238
67 + 103171 = 103238
97 + 103141 = 103238
139 + 103099 = 103238
151 + 103087 = 103238
271 + 102967 = 103238
307 + 102931 = 103238

Showing the first eight; more decompositions exist.
