Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39860, here are decompositions:

3 + 39857 = 39860
13 + 39847 = 39860
19 + 39841 = 39860
31 + 39829 = 39860
61 + 39799 = 39860
127 + 39733 = 39860
151 + 39709 = 39860
157 + 39703 = 39860

Showing the first eight; more decompositions exist.
