Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611908, here are decompositions:

5 + 8611903 = 8611908
17 + 8611891 = 8611908
29 + 8611879 = 8611908
59 + 8611849 = 8611908
61 + 8611847 = 8611908
79 + 8611829 = 8611908
89 + 8611819 = 8611908
199 + 8611709 = 8611908

Showing the first eight; more decompositions exist.
