Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47340, here are decompositions:

23 + 47317 = 47340
31 + 47309 = 47340
37 + 47303 = 47340
43 + 47297 = 47340
47 + 47293 = 47340
53 + 47287 = 47340
61 + 47279 = 47340
71 + 47269 = 47340

Showing the first eight; more decompositions exist.
