Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542728, here are decompositions:

5 + 542723 = 542728
41 + 542687 = 542728
149 + 542579 = 542728
191 + 542537 = 542728
239 + 542489 = 542728
281 + 542447 = 542728
467 + 542261 = 542728
491 + 542237 = 542728

Showing the first eight; more decompositions exist.
