Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142458, here are decompositions:

5 + 142453 = 142458
31 + 142427 = 142458
37 + 142421 = 142458
67 + 142391 = 142458
89 + 142369 = 142458
101 + 142357 = 142458
131 + 142327 = 142458
139 + 142319 = 142458

Showing the first eight; more decompositions exist.
