Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542548, here are decompositions:

11 + 542537 = 542548
29 + 542519 = 542548
59 + 542489 = 542548
101 + 542447 = 542548
107 + 542441 = 542548
311 + 542237 = 542548
359 + 542189 = 542548
431 + 542117 = 542548

Showing the first eight; more decompositions exist.
