Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172416, here are decompositions:

5 + 172411 = 172416
17 + 172399 = 172416
43 + 172373 = 172416
59 + 172357 = 172416
73 + 172343 = 172416
103 + 172313 = 172416
109 + 172307 = 172416
137 + 172279 = 172416

Showing the first eight; more decompositions exist.
