Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680272, here are decompositions:

5 + 8680267 = 8680272
23 + 8680249 = 8680272
43 + 8680229 = 8680272
53 + 8680219 = 8680272
59 + 8680213 = 8680272
71 + 8680201 = 8680272
101 + 8680171 = 8680272
151 + 8680121 = 8680272

Showing the first eight; more decompositions exist.
