Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542458, here are decompositions:

11 + 542447 = 542458
17 + 542441 = 542458
197 + 542261 = 542458
239 + 542219 = 542458
251 + 542207 = 542458
269 + 542189 = 542458
317 + 542141 = 542458
347 + 542111 = 542458

Showing the first eight; more decompositions exist.
