Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39872, here are decompositions:

3 + 39869 = 39872
31 + 39841 = 39872
43 + 39829 = 39872
73 + 39799 = 39872
103 + 39769 = 39872
139 + 39733 = 39872
163 + 39709 = 39872
193 + 39679 = 39872

Showing the first eight; more decompositions exist.
