Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542164, here are decompositions:

11 + 542153 = 542164
23 + 542141 = 542164
41 + 542123 = 542164
47 + 542117 = 542164
53 + 542111 = 542164
71 + 542093 = 542164
83 + 542081 = 542164
101 + 542063 = 542164

Showing the first eight; more decompositions exist.
