Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680842, here are decompositions:

19 + 8680823 = 8680842
29 + 8680813 = 8680842
31 + 8680811 = 8680842
41 + 8680801 = 8680842
61 + 8680781 = 8680842
73 + 8680769 = 8680842
89 + 8680753 = 8680842
101 + 8680741 = 8680842

Showing the first eight; more decompositions exist.
