Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103406, here are decompositions:

7 + 103399 = 103406
13 + 103393 = 103406
19 + 103387 = 103406
73 + 103333 = 103406
223 + 103183 = 103406
229 + 103177 = 103406
283 + 103123 = 103406
307 + 103099 = 103406

Showing the first eight; more decompositions exist.
