Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542112, here are decompositions:

19 + 542093 = 542112
29 + 542083 = 542112
31 + 542081 = 542112
41 + 542071 = 542112
59 + 542053 = 542112
89 + 542023 = 542112
113 + 541999 = 542112
211 + 541901 = 542112

Showing the first eight; more decompositions exist.
