Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542140, here are decompositions:

17 + 542123 = 542140
23 + 542117 = 542140
29 + 542111 = 542140
47 + 542093 = 542140
59 + 542081 = 542140
113 + 542027 = 542140
149 + 541991 = 542140
173 + 541967 = 542140

Showing the first eight; more decompositions exist.
