Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103388, here are decompositions:

31 + 103357 = 103388
97 + 103291 = 103388
151 + 103237 = 103388
157 + 103231 = 103388
211 + 103177 = 103388
421 + 102967 = 103388
457 + 102931 = 103388
547 + 102841 = 103388

Showing the first eight; more decompositions exist.
