Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47130, here are decompositions:

7 + 47123 = 47130
11 + 47119 = 47130
19 + 47111 = 47130
37 + 47093 = 47130
43 + 47087 = 47130
71 + 47059 = 47130
73 + 47057 = 47130
79 + 47051 = 47130

Showing the first eight; more decompositions exist.
