Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47720, here are decompositions:

3 + 47717 = 47720
7 + 47713 = 47720
19 + 47701 = 47720
61 + 47659 = 47720
67 + 47653 = 47720
97 + 47623 = 47720
139 + 47581 = 47720
151 + 47569 = 47720

Showing the first eight; more decompositions exist.
