Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172658, here are decompositions:

61 + 172597 = 172658
97 + 172561 = 172658
139 + 172519 = 172658
151 + 172507 = 172658
307 + 172351 = 172658
337 + 172321 = 172658
379 + 172279 = 172658
439 + 172219 = 172658

Showing the first eight; more decompositions exist.
