Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47930, here are decompositions:

13 + 47917 = 47930
19 + 47911 = 47930
61 + 47869 = 47930
73 + 47857 = 47930
139 + 47791 = 47930
151 + 47779 = 47930
193 + 47737 = 47930
229 + 47701 = 47930

Showing the first eight; more decompositions exist.
