Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47140, here are decompositions:

3 + 47137 = 47140
11 + 47129 = 47140
17 + 47123 = 47140
29 + 47111 = 47140
47 + 47093 = 47140
53 + 47087 = 47140
83 + 47057 = 47140
89 + 47051 = 47140

Showing the first eight; more decompositions exist.
