Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142398, here are decompositions:

7 + 142391 = 142398
17 + 142381 = 142398
29 + 142369 = 142398
41 + 142357 = 142398
71 + 142327 = 142398
79 + 142319 = 142398
101 + 142297 = 142398
127 + 142271 = 142398

Showing the first eight; more decompositions exist.
