Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680394, here are decompositions:

3 + 8680391 = 8680394
67 + 8680327 = 8680394
97 + 8680297 = 8680394
127 + 8680267 = 8680394
181 + 8680213 = 8680394
193 + 8680201 = 8680394
223 + 8680171 = 8680394
241 + 8680153 = 8680394

Showing the first eight; more decompositions exist.
