Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542208, here are decompositions:

11 + 542197 = 542208
19 + 542189 = 542208
41 + 542167 = 542208
59 + 542149 = 542208
67 + 542141 = 542208
89 + 542119 = 542208
97 + 542111 = 542208
127 + 542081 = 542208

Showing the first eight; more decompositions exist.
