Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102938, here are decompositions:

7 + 102931 = 102938
61 + 102877 = 102938
67 + 102871 = 102938
79 + 102859 = 102938
97 + 102841 = 102938
109 + 102829 = 102938
127 + 102811 = 102938
271 + 102667 = 102938

Showing the first eight; more decompositions exist.
