Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47870, here are decompositions:

13 + 47857 = 47870
61 + 47809 = 47870
73 + 47797 = 47870
79 + 47791 = 47870
127 + 47743 = 47870
157 + 47713 = 47870
211 + 47659 = 47870
241 + 47629 = 47870

Showing the first eight; more decompositions exist.
