Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142368, here are decompositions:

11 + 142357 = 142368
41 + 142327 = 142368
71 + 142297 = 142368
97 + 142271 = 142368
131 + 142237 = 142368
137 + 142231 = 142368
151 + 142217 = 142368
157 + 142211 = 142368

Showing the first eight; more decompositions exist.
