Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611998, here are decompositions:

7 + 8611991 = 8611998
11 + 8611987 = 8611998
29 + 8611969 = 8611998
37 + 8611961 = 8611998
107 + 8611891 = 8611998
139 + 8611859 = 8611998
149 + 8611849 = 8611998
151 + 8611847 = 8611998

Showing the first eight; more decompositions exist.
