Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172268, here are decompositions:

97 + 172171 = 172268
199 + 172069 = 172268
241 + 172027 = 172268
331 + 171937 = 172268
379 + 171889 = 172268
457 + 171811 = 172268
571 + 171697 = 172268
631 + 171637 = 172268

Showing the first eight; more decompositions exist.
