Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11748, here are decompositions:

5 + 11743 = 11748
17 + 11731 = 11748
29 + 11719 = 11748
31 + 11717 = 11748
47 + 11701 = 11748
59 + 11689 = 11748
67 + 11681 = 11748
71 + 11677 = 11748

Showing the first eight; more decompositions exist.
