Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611800, here are decompositions:

7 + 8611793 = 8611800
11 + 8611789 = 8611800
17 + 8611783 = 8611800
79 + 8611721 = 8611800
97 + 8611703 = 8611800
103 + 8611697 = 8611800
137 + 8611663 = 8611800
157 + 8611643 = 8611800

Showing the first eight; more decompositions exist.
