Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680398, here are decompositions:

7 + 8680391 = 8680398
19 + 8680379 = 8680398
29 + 8680369 = 8680398
61 + 8680337 = 8680398
71 + 8680327 = 8680398
101 + 8680297 = 8680398
131 + 8680267 = 8680398
149 + 8680249 = 8680398

Showing the first eight; more decompositions exist.
