Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542172, here are decompositions:

5 + 542167 = 542172
19 + 542153 = 542172
23 + 542149 = 542172
31 + 542141 = 542172
41 + 542131 = 542172
53 + 542119 = 542172
61 + 542111 = 542172
79 + 542093 = 542172

Showing the first eight; more decompositions exist.
