Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39854, here are decompositions:

7 + 39847 = 39854
13 + 39841 = 39854
127 + 39727 = 39854
151 + 39703 = 39854
223 + 39631 = 39854
313 + 39541 = 39854
457 + 39397 = 39854
487 + 39367 = 39854

Showing the first eight; more decompositions exist.
