Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1214, here are decompositions:

13 + 1201 = 1214
43 + 1171 = 1214
61 + 1153 = 1214
97 + 1117 = 1214
127 + 1087 = 1214
151 + 1063 = 1214
163 + 1051 = 1214
181 + 1033 = 1214

Showing the first eight; more decompositions exist.
