Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47730, here are decompositions:

13 + 47717 = 47730
17 + 47713 = 47730
19 + 47711 = 47730
29 + 47701 = 47730
31 + 47699 = 47730
71 + 47659 = 47730
73 + 47657 = 47730
101 + 47629 = 47730

Showing the first eight; more decompositions exist.
