Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542550, here are decompositions:

11 + 542539 = 542550
13 + 542537 = 542550
17 + 542533 = 542550
31 + 542519 = 542550
53 + 542497 = 542550
61 + 542489 = 542550
67 + 542483 = 542550
83 + 542467 = 542550

Showing the first eight; more decompositions exist.
