Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142086, here are decompositions:

19 + 142067 = 142086
29 + 142057 = 142086
37 + 142049 = 142086
47 + 142039 = 142086
67 + 142019 = 142086
79 + 142007 = 142086
127 + 141959 = 142086
149 + 141937 = 142086

Showing the first eight; more decompositions exist.
