Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39142, here are decompositions:

3 + 39139 = 39142
23 + 39119 = 39142
29 + 39113 = 39142
53 + 39089 = 39142
101 + 39041 = 39142
149 + 38993 = 39142
239 + 38903 = 39142
251 + 38891 = 39142

Showing the first eight; more decompositions exist.
