Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142404, here are decompositions:

13 + 142391 = 142404
23 + 142381 = 142404
47 + 142357 = 142404
107 + 142297 = 142404
167 + 142237 = 142404
173 + 142231 = 142404
181 + 142223 = 142404
193 + 142211 = 142404

Showing the first eight; more decompositions exist.
