Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542520, here are decompositions:

23 + 542497 = 542520
31 + 542489 = 542520
37 + 542483 = 542520
53 + 542467 = 542520
59 + 542461 = 542520
73 + 542447 = 542520
79 + 542441 = 542520
149 + 542371 = 542520

Showing the first eight; more decompositions exist.
