Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542158, here are decompositions:

5 + 542153 = 542158
17 + 542141 = 542158
41 + 542117 = 542158
47 + 542111 = 542158
131 + 542027 = 542158
137 + 542021 = 542158
167 + 541991 = 542158
191 + 541967 = 542158

Showing the first eight; more decompositions exist.
