Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542406, here are decompositions:

5 + 542401 = 542406
83 + 542323 = 542406
107 + 542299 = 542406
113 + 542293 = 542406
199 + 542207 = 542406
223 + 542183 = 542406
239 + 542167 = 542406
257 + 542149 = 542406

Showing the first eight; more decompositions exist.
