Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542908, here are decompositions:

17 + 542891 = 542908
71 + 542837 = 542908
137 + 542771 = 542908
389 + 542519 = 542908
419 + 542489 = 542908
461 + 542447 = 542908
467 + 542441 = 542908
647 + 542261 = 542908

Showing the first eight; more decompositions exist.
