Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742876, here are decompositions:

19 + 8742857 = 8742876
29 + 8742847 = 8742876
59 + 8742817 = 8742876
89 + 8742787 = 8742876
97 + 8742779 = 8742876
137 + 8742739 = 8742876
199 + 8742677 = 8742876
223 + 8742653 = 8742876

Showing the first eight; more decompositions exist.
