Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1374, here are decompositions:

7 + 1367 = 1374
13 + 1361 = 1374
47 + 1327 = 1374
53 + 1321 = 1374
67 + 1307 = 1374
71 + 1303 = 1374
73 + 1301 = 1374
83 + 1291 = 1374

Showing the first eight; more decompositions exist.
