Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142524, here are decompositions:

23 + 142501 = 142524
71 + 142453 = 142524
97 + 142427 = 142524
103 + 142421 = 142524
167 + 142357 = 142524
197 + 142327 = 142524
227 + 142297 = 142524
293 + 142231 = 142524

Showing the first eight; more decompositions exist.
