Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680408, here are decompositions:

17 + 8680391 = 8680408
29 + 8680379 = 8680408
71 + 8680337 = 8680408
101 + 8680307 = 8680408
131 + 8680277 = 8680408
179 + 8680229 = 8680408
251 + 8680157 = 8680408
509 + 8679899 = 8680408

Showing the first eight; more decompositions exist.
