Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542148, here are decompositions:

7 + 542141 = 542148
17 + 542131 = 542148
29 + 542119 = 542148
31 + 542117 = 542148
37 + 542111 = 542148
67 + 542081 = 542148
127 + 542021 = 542148
149 + 541999 = 542148

Showing the first eight; more decompositions exist.
