Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172374, here are decompositions:

17 + 172357 = 172374
23 + 172351 = 172374
31 + 172343 = 172374
43 + 172331 = 172374
53 + 172321 = 172374
61 + 172313 = 172374
67 + 172307 = 172374
131 + 172243 = 172374

Showing the first eight; more decompositions exist.
