Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124512, here are decompositions:

19 + 124493 = 124512
23 + 124489 = 124512
41 + 124471 = 124512
53 + 124459 = 124512
79 + 124433 = 124512
83 + 124429 = 124512
149 + 124363 = 124512
163 + 124349 = 124512

Showing the first eight; more decompositions exist.
