Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172352, here are decompositions:

31 + 172321 = 172352
73 + 172279 = 172352
109 + 172243 = 172352
139 + 172213 = 172352
181 + 172171 = 172352
199 + 172153 = 172352
283 + 172069 = 172352
331 + 172021 = 172352

Showing the first eight; more decompositions exist.
