Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103408, here are decompositions:

17 + 103391 = 103408
59 + 103349 = 103408
89 + 103319 = 103408
101 + 103307 = 103408
191 + 103217 = 103408
317 + 103091 = 103408
359 + 103049 = 103408
401 + 103007 = 103408

Showing the first eight; more decompositions exist.
