Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103386, here are decompositions:

29 + 103357 = 103386
37 + 103349 = 103386
53 + 103333 = 103386
67 + 103319 = 103386
79 + 103307 = 103386
97 + 103289 = 103386
149 + 103237 = 103386
263 + 103123 = 103386

Showing the first eight; more decompositions exist.
