Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103506, here are decompositions:

23 + 103483 = 103506
83 + 103423 = 103506
97 + 103409 = 103506
107 + 103399 = 103506
113 + 103393 = 103506
149 + 103357 = 103506
157 + 103349 = 103506
173 + 103333 = 103506

Showing the first eight; more decompositions exist.
