Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8144, here are decompositions:

43 + 8101 = 8144
127 + 8017 = 8144
151 + 7993 = 8144
181 + 7963 = 8144
193 + 7951 = 8144
211 + 7933 = 8144
271 + 7873 = 8144
277 + 7867 = 8144

Showing the first eight; more decompositions exist.
