Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71172, here are decompositions:

5 + 71167 = 71172
11 + 71161 = 71172
19 + 71153 = 71172
29 + 71143 = 71172
43 + 71129 = 71172
53 + 71119 = 71172
83 + 71089 = 71172
103 + 71069 = 71172

Showing the first eight; more decompositions exist.
