Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611980, here are decompositions:

11 + 8611969 = 8611980
19 + 8611961 = 8611980
89 + 8611891 = 8611980
101 + 8611879 = 8611980
107 + 8611873 = 8611980
131 + 8611849 = 8611980
151 + 8611829 = 8611980
191 + 8611789 = 8611980

Showing the first eight; more decompositions exist.
