Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123672, here are decompositions:

5 + 123667 = 123672
11 + 123661 = 123672
19 + 123653 = 123672
41 + 123631 = 123672
53 + 123619 = 123672
71 + 123601 = 123672
79 + 123593 = 123672
89 + 123583 = 123672

Showing the first eight; more decompositions exist.
