Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542028, here are decompositions:

5 + 542023 = 542028
7 + 542021 = 542028
29 + 541999 = 542028
37 + 541991 = 542028
41 + 541987 = 542028
61 + 541967 = 542028
101 + 541927 = 542028
127 + 541901 = 542028

Showing the first eight; more decompositions exist.
