Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611804, here are decompositions:

11 + 8611793 = 8611804
83 + 8611721 = 8611804
101 + 8611703 = 8611804
107 + 8611697 = 8611804
137 + 8611667 = 8611804
191 + 8611613 = 8611804
281 + 8611523 = 8611804
317 + 8611487 = 8611804

Showing the first eight; more decompositions exist.
