Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170372, here are decompositions:

3 + 170369 = 170372
19 + 170353 = 170372
31 + 170341 = 170372
73 + 170299 = 170372
79 + 170293 = 170372
109 + 170263 = 170372
193 + 170179 = 170372
271 + 170101 = 170372

Showing the first eight; more decompositions exist.
