Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172354, here are decompositions:

3 + 172351 = 172354
11 + 172343 = 172354
23 + 172331 = 172354
41 + 172313 = 172354
47 + 172307 = 172354
71 + 172283 = 172354
131 + 172223 = 172354
137 + 172217 = 172354

Showing the first eight; more decompositions exist.
