Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672272, here are decompositions:

5 + 8672267 = 8672272
71 + 8672201 = 8672272
173 + 8672099 = 8672272
269 + 8672003 = 8672272
281 + 8671991 = 8672272
293 + 8671979 = 8672272
353 + 8671919 = 8672272
461 + 8671811 = 8672272

Showing the first eight; more decompositions exist.
