Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542544, here are decompositions:

5 + 542539 = 542544
7 + 542537 = 542544
11 + 542533 = 542544
47 + 542497 = 542544
61 + 542483 = 542544
83 + 542461 = 542544
97 + 542447 = 542544
103 + 542441 = 542544

Showing the first eight; more decompositions exist.
