Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1454, here are decompositions:

3 + 1451 = 1454
7 + 1447 = 1454
31 + 1423 = 1454
73 + 1381 = 1454
127 + 1327 = 1454
151 + 1303 = 1454
157 + 1297 = 1454
163 + 1291 = 1454

Showing the first eight; more decompositions exist.
