Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529172, here are decompositions:

19 + 529153 = 529172
43 + 529129 = 529172
139 + 529033 = 529172
181 + 528991 = 529172
199 + 528973 = 529172
349 + 528823 = 529172
373 + 528799 = 529172
409 + 528763 = 529172

Showing the first eight; more decompositions exist.
