Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671272, here are decompositions:

23 + 8671249 = 8671272
41 + 8671231 = 8671272
53 + 8671219 = 8671272
79 + 8671193 = 8671272
139 + 8671133 = 8671272
173 + 8671099 = 8671272
241 + 8671031 = 8671272
263 + 8671009 = 8671272

Showing the first eight; more decompositions exist.
