Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142536, here are decompositions:

7 + 142529 = 142536
67 + 142469 = 142536
83 + 142453 = 142536
103 + 142433 = 142536
109 + 142427 = 142536
167 + 142369 = 142536
179 + 142357 = 142536
239 + 142297 = 142536

Showing the first eight; more decompositions exist.
