Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39866, here are decompositions:

3 + 39863 = 39866
19 + 39847 = 39866
37 + 39829 = 39866
67 + 39799 = 39866
97 + 39769 = 39866
139 + 39727 = 39866
157 + 39709 = 39866
163 + 39703 = 39866

Showing the first eight; more decompositions exist.
