Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172412, here are decompositions:

13 + 172399 = 172412
61 + 172351 = 172412
193 + 172219 = 172412
199 + 172213 = 172412
241 + 172171 = 172412
523 + 171889 = 172412
601 + 171811 = 172412
613 + 171799 = 172412

Showing the first eight; more decompositions exist.
