Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542556, here are decompositions:

5 + 542551 = 542556
17 + 542539 = 542556
19 + 542537 = 542556
23 + 542533 = 542556
37 + 542519 = 542556
59 + 542497 = 542556
67 + 542489 = 542556
73 + 542483 = 542556

Showing the first eight; more decompositions exist.
