Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123408, here are decompositions:

7 + 123401 = 123408
11 + 123397 = 123408
29 + 123379 = 123408
31 + 123377 = 123408
67 + 123341 = 123408
97 + 123311 = 123408
101 + 123307 = 123408
139 + 123269 = 123408

Showing the first eight; more decompositions exist.
