Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680528, here are decompositions:

47 + 8680481 = 8680528
89 + 8680439 = 8680528
137 + 8680391 = 8680528
149 + 8680379 = 8680528
191 + 8680337 = 8680528
251 + 8680277 = 8680528
491 + 8680037 = 8680528
557 + 8679971 = 8680528

Showing the first eight; more decompositions exist.
