Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10172, here are decompositions:

3 + 10169 = 10172
13 + 10159 = 10172
31 + 10141 = 10172
61 + 10111 = 10172
73 + 10099 = 10172
79 + 10093 = 10172
103 + 10069 = 10172
163 + 10009 = 10172

Showing the first eight; more decompositions exist.
