Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142598, here are decompositions:

7 + 142591 = 142598
31 + 142567 = 142598
61 + 142537 = 142598
97 + 142501 = 142598
229 + 142369 = 142598
241 + 142357 = 142598
271 + 142327 = 142598
367 + 142231 = 142598

Showing the first eight; more decompositions exist.
