Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611876, here are decompositions:

3 + 8611873 = 8611876
17 + 8611859 = 8611876
29 + 8611847 = 8611876
47 + 8611829 = 8611876
83 + 8611793 = 8611876
167 + 8611709 = 8611876
173 + 8611703 = 8611876
179 + 8611697 = 8611876

Showing the first eight; more decompositions exist.
