Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172350, here are decompositions:

7 + 172343 = 172350
19 + 172331 = 172350
29 + 172321 = 172350
37 + 172313 = 172350
43 + 172307 = 172350
53 + 172297 = 172350
67 + 172283 = 172350
71 + 172279 = 172350

Showing the first eight; more decompositions exist.
