Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1394, here are decompositions:

13 + 1381 = 1394
67 + 1327 = 1394
73 + 1321 = 1394
97 + 1297 = 1394
103 + 1291 = 1394
157 + 1237 = 1394
163 + 1231 = 1394
181 + 1213 = 1394

Showing the first eight; more decompositions exist.
