Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680356, here are decompositions:

19 + 8680337 = 8680356
29 + 8680327 = 8680356
43 + 8680313 = 8680356
53 + 8680303 = 8680356
59 + 8680297 = 8680356
79 + 8680277 = 8680356
89 + 8680267 = 8680356
107 + 8680249 = 8680356

Showing the first eight; more decompositions exist.
