Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11828, here are decompositions:

7 + 11821 = 11828
97 + 11731 = 11828
109 + 11719 = 11828
127 + 11701 = 11828
139 + 11689 = 11828
151 + 11677 = 11828
211 + 11617 = 11828
241 + 11587 = 11828

Showing the first eight; more decompositions exist.
