Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11888, here are decompositions:

61 + 11827 = 11888
67 + 11821 = 11888
109 + 11779 = 11888
157 + 11731 = 11888
199 + 11689 = 11888
211 + 11677 = 11888
271 + 11617 = 11888
337 + 11551 = 11888

Showing the first eight; more decompositions exist.
