Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39824, here are decompositions:

3 + 39821 = 39824
97 + 39727 = 39824
157 + 39667 = 39824
193 + 39631 = 39824
283 + 39541 = 39824
313 + 39511 = 39824
373 + 39451 = 39824
457 + 39367 = 39824

Showing the first eight; more decompositions exist.
