Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680542, here are decompositions:

29 + 8680513 = 8680542
41 + 8680501 = 8680542
61 + 8680481 = 8680542
71 + 8680471 = 8680542
103 + 8680439 = 8680542
151 + 8680391 = 8680542
163 + 8680379 = 8680542
173 + 8680369 = 8680542

Showing the first eight; more decompositions exist.
