Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172876, here are decompositions:

5 + 172871 = 172876
17 + 172859 = 172876
23 + 172853 = 172876
47 + 172829 = 172876
89 + 172787 = 172876
167 + 172709 = 172876
227 + 172649 = 172876
233 + 172643 = 172876

Showing the first eight; more decompositions exist.
