Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542486, here are decompositions:

3 + 542483 = 542486
19 + 542467 = 542486
163 + 542323 = 542486
193 + 542293 = 542486
223 + 542263 = 542486
337 + 542149 = 542486
367 + 542119 = 542486
433 + 542053 = 542486

Showing the first eight; more decompositions exist.
