Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680556, here are decompositions:

13 + 8680543 = 8680556
43 + 8680513 = 8680556
139 + 8680417 = 8680556
229 + 8680327 = 8680556
307 + 8680249 = 8680556
337 + 8680219 = 8680556
457 + 8680099 = 8680556
523 + 8680033 = 8680556

Showing the first eight; more decompositions exist.
