Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142518, here are decompositions:

17 + 142501 = 142518
97 + 142421 = 142518
127 + 142391 = 142518
137 + 142381 = 142518
149 + 142369 = 142518
191 + 142327 = 142518
199 + 142319 = 142518
281 + 142237 = 142518

Showing the first eight; more decompositions exist.
