Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172308, here are decompositions:

11 + 172297 = 172308
29 + 172279 = 172308
89 + 172219 = 172308
109 + 172199 = 172308
127 + 172181 = 172308
137 + 172171 = 172308
139 + 172169 = 172308
151 + 172157 = 172308

Showing the first eight; more decompositions exist.
