Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142494, here are decompositions:

41 + 142453 = 142494
61 + 142433 = 142494
67 + 142427 = 142494
73 + 142421 = 142494
103 + 142391 = 142494
113 + 142381 = 142494
137 + 142357 = 142494
167 + 142327 = 142494

Showing the first eight; more decompositions exist.
