Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39180, here are decompositions:

17 + 39163 = 39180
19 + 39161 = 39180
23 + 39157 = 39180
41 + 39139 = 39180
47 + 39133 = 39180
61 + 39119 = 39180
67 + 39113 = 39180
73 + 39107 = 39180

Showing the first eight; more decompositions exist.
