Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542286, here are decompositions:

5 + 542281 = 542286
23 + 542263 = 542286
67 + 542219 = 542286
79 + 542207 = 542286
89 + 542197 = 542286
97 + 542189 = 542286
103 + 542183 = 542286
137 + 542149 = 542286

Showing the first eight; more decompositions exist.
