Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680488, here are decompositions:

7 + 8680481 = 8680488
17 + 8680471 = 8680488
71 + 8680417 = 8680488
79 + 8680409 = 8680488
97 + 8680391 = 8680488
109 + 8680379 = 8680488
151 + 8680337 = 8680488
181 + 8680307 = 8680488

Showing the first eight; more decompositions exist.
