Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11738, here are decompositions:

7 + 11731 = 11738
19 + 11719 = 11738
37 + 11701 = 11738
61 + 11677 = 11738
151 + 11587 = 11738
211 + 11527 = 11738
241 + 11497 = 11738
271 + 11467 = 11738

Showing the first eight; more decompositions exist.
