Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47858, here are decompositions:

61 + 47797 = 47858
67 + 47791 = 47858
79 + 47779 = 47858
157 + 47701 = 47858
199 + 47659 = 47858
229 + 47629 = 47858
277 + 47581 = 47858
331 + 47527 = 47858

Showing the first eight; more decompositions exist.
