Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172330, here are decompositions:

17 + 172313 = 172330
23 + 172307 = 172330
47 + 172283 = 172330
71 + 172259 = 172330
107 + 172223 = 172330
113 + 172217 = 172330
131 + 172199 = 172330
149 + 172181 = 172330

Showing the first eight; more decompositions exist.
