Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172358, here are decompositions:

7 + 172351 = 172358
37 + 172321 = 172358
61 + 172297 = 172358
79 + 172279 = 172358
139 + 172219 = 172358
211 + 172147 = 172358
331 + 172027 = 172358
337 + 172021 = 172358

Showing the first eight; more decompositions exist.
