Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542506, here are decompositions:

17 + 542489 = 542506
23 + 542483 = 542506
59 + 542447 = 542506
269 + 542237 = 542506
317 + 542189 = 542506
353 + 542153 = 542506
383 + 542123 = 542506
389 + 542117 = 542506

Showing the first eight; more decompositions exist.
