Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665976, here are decompositions:

3 + 8665973 = 8665976
37 + 8665939 = 8665976
43 + 8665933 = 8665976
79 + 8665897 = 8665976
103 + 8665873 = 8665976
127 + 8665849 = 8665976
199 + 8665777 = 8665976
373 + 8665603 = 8665976

Showing the first eight; more decompositions exist.
