Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123506, here are decompositions:

3 + 123503 = 123506
7 + 123499 = 123506
13 + 123493 = 123506
67 + 123439 = 123506
73 + 123433 = 123506
79 + 123427 = 123506
109 + 123397 = 123506
127 + 123379 = 123506

Showing the first eight; more decompositions exist.
