Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47878, here are decompositions:

41 + 47837 = 47878
59 + 47819 = 47878
71 + 47807 = 47878
101 + 47777 = 47878
137 + 47741 = 47878
167 + 47711 = 47878
179 + 47699 = 47878
197 + 47681 = 47878

Showing the first eight; more decompositions exist.
