Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39956, here are decompositions:

3 + 39953 = 39956
19 + 39937 = 39956
73 + 39883 = 39956
79 + 39877 = 39956
109 + 39847 = 39956
127 + 39829 = 39956
157 + 39799 = 39956
223 + 39733 = 39956

Showing the first eight; more decompositions exist.
