Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542154, here are decompositions:

5 + 542149 = 542154
13 + 542141 = 542154
23 + 542131 = 542154
31 + 542123 = 542154
37 + 542117 = 542154
43 + 542111 = 542154
61 + 542093 = 542154
71 + 542083 = 542154

Showing the first eight; more decompositions exist.
