Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172252, here are decompositions:

29 + 172223 = 172252
53 + 172199 = 172252
71 + 172181 = 172252
83 + 172169 = 172252
173 + 172079 = 172252
251 + 172001 = 172252
383 + 171869 = 172252
389 + 171863 = 172252

Showing the first eight; more decompositions exist.
