Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542508, here are decompositions:

11 + 542497 = 542508
19 + 542489 = 542508
41 + 542467 = 542508
47 + 542461 = 542508
61 + 542447 = 542508
67 + 542441 = 542508
107 + 542401 = 542508
137 + 542371 = 542508

Showing the first eight; more decompositions exist.
