Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680380, here are decompositions:

11 + 8680369 = 8680380
43 + 8680337 = 8680380
53 + 8680327 = 8680380
67 + 8680313 = 8680380
73 + 8680307 = 8680380
83 + 8680297 = 8680380
103 + 8680277 = 8680380
113 + 8680267 = 8680380

Showing the first eight; more decompositions exist.
