Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542518, here are decompositions:

29 + 542489 = 542518
71 + 542447 = 542518
257 + 542261 = 542518
281 + 542237 = 542518
311 + 542207 = 542518
401 + 542117 = 542518
491 + 542027 = 542518
617 + 541901 = 542518

Showing the first eight; more decompositions exist.
