Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40878, here are decompositions:

11 + 40867 = 40878
29 + 40849 = 40878
31 + 40847 = 40878
37 + 40841 = 40878
59 + 40819 = 40878
107 + 40771 = 40878
127 + 40751 = 40878
139 + 40739 = 40878

Showing the first eight; more decompositions exist.
