Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542170, here are decompositions:

3 + 542167 = 542170
17 + 542153 = 542170
29 + 542141 = 542170
47 + 542123 = 542170
53 + 542117 = 542170
59 + 542111 = 542170
89 + 542081 = 542170
107 + 542063 = 542170

Showing the first eight; more decompositions exist.
