Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142434, here are decompositions:

7 + 142427 = 142434
13 + 142421 = 142434
31 + 142403 = 142434
43 + 142391 = 142434
53 + 142381 = 142434
107 + 142327 = 142434
137 + 142297 = 142434
163 + 142271 = 142434

Showing the first eight; more decompositions exist.
