Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47818, here are decompositions:

11 + 47807 = 47818
41 + 47777 = 47818
101 + 47717 = 47818
107 + 47711 = 47818
137 + 47681 = 47818
179 + 47639 = 47818
227 + 47591 = 47818
311 + 47507 = 47818

Showing the first eight; more decompositions exist.
