Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542142, here are decompositions:

11 + 542131 = 542142
19 + 542123 = 542142
23 + 542119 = 542142
31 + 542111 = 542142
59 + 542083 = 542142
61 + 542081 = 542142
71 + 542071 = 542142
79 + 542063 = 542142

Showing the first eight; more decompositions exist.
