Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123450, here are decompositions:

11 + 123439 = 123450
17 + 123433 = 123450
23 + 123427 = 123450
31 + 123419 = 123450
43 + 123407 = 123450
53 + 123397 = 123450
71 + 123379 = 123450
73 + 123377 = 123450

Showing the first eight; more decompositions exist.
