Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123748, here are decompositions:

11 + 123737 = 123748
17 + 123731 = 123748
29 + 123719 = 123748
41 + 123707 = 123748
47 + 123701 = 123748
71 + 123677 = 123748
167 + 123581 = 123748
197 + 123551 = 123748

Showing the first eight; more decompositions exist.
