Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1434, here are decompositions:

5 + 1429 = 1434
7 + 1427 = 1434
11 + 1423 = 1434
53 + 1381 = 1434
61 + 1373 = 1434
67 + 1367 = 1434
73 + 1361 = 1434
107 + 1327 = 1434

Showing the first eight; more decompositions exist.
