Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123430, here are decompositions:

3 + 123427 = 123430
11 + 123419 = 123430
23 + 123407 = 123430
29 + 123401 = 123430
53 + 123377 = 123430
89 + 123341 = 123430
107 + 123323 = 123430
191 + 123239 = 123430

Showing the first eight; more decompositions exist.
