Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142374, here are decompositions:

5 + 142369 = 142374
17 + 142357 = 142374
47 + 142327 = 142374
103 + 142271 = 142374
137 + 142237 = 142374
151 + 142223 = 142374
157 + 142217 = 142374
163 + 142211 = 142374

Showing the first eight; more decompositions exist.
