Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542136, here are decompositions:

5 + 542131 = 542136
13 + 542123 = 542136
17 + 542119 = 542136
19 + 542117 = 542136
43 + 542093 = 542136
53 + 542083 = 542136
73 + 542063 = 542136
83 + 542053 = 542136

Showing the first eight; more decompositions exist.
