Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680340, here are decompositions:

3 + 8680337 = 8680340
13 + 8680327 = 8680340
37 + 8680303 = 8680340
43 + 8680297 = 8680340
73 + 8680267 = 8680340
127 + 8680213 = 8680340
139 + 8680201 = 8680340
241 + 8680099 = 8680340

Showing the first eight; more decompositions exist.
