Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47172, here are decompositions:

11 + 47161 = 47172
23 + 47149 = 47172
29 + 47143 = 47172
43 + 47129 = 47172
53 + 47119 = 47172
61 + 47111 = 47172
79 + 47093 = 47172
113 + 47059 = 47172

Showing the first eight; more decompositions exist.
