Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680402, here are decompositions:

11 + 8680391 = 8680402
23 + 8680379 = 8680402
89 + 8680313 = 8680402
173 + 8680229 = 8680402
281 + 8680121 = 8680402
359 + 8680043 = 8680402
431 + 8679971 = 8680402
449 + 8679953 = 8680402

Showing the first eight; more decompositions exist.
