Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39878, here are decompositions:

31 + 39847 = 39878
37 + 39841 = 39878
79 + 39799 = 39878
109 + 39769 = 39878
151 + 39727 = 39878
199 + 39679 = 39878
211 + 39667 = 39878
271 + 39607 = 39878

Showing the first eight; more decompositions exist.
