Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172262, here are decompositions:

3 + 172259 = 172262
19 + 172243 = 172262
43 + 172219 = 172262
109 + 172153 = 172262
193 + 172069 = 172262
241 + 172021 = 172262
373 + 171889 = 172262
439 + 171823 = 172262

Showing the first eight; more decompositions exist.
