Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11864, here are decompositions:

31 + 11833 = 11864
37 + 11827 = 11864
43 + 11821 = 11864
163 + 11701 = 11864
271 + 11593 = 11864
277 + 11587 = 11864
313 + 11551 = 11864
337 + 11527 = 11864

Showing the first eight; more decompositions exist.
