Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172678, here are decompositions:

5 + 172673 = 172678
29 + 172649 = 172678
59 + 172619 = 172678
71 + 172607 = 172678
89 + 172589 = 172678
137 + 172541 = 172678
239 + 172439 = 172678
251 + 172427 = 172678

Showing the first eight; more decompositions exist.
