Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611824, here are decompositions:

5 + 8611819 = 8611824
31 + 8611793 = 8611824
41 + 8611783 = 8611824
101 + 8611723 = 8611824
103 + 8611721 = 8611824
127 + 8611697 = 8611824
157 + 8611667 = 8611824
181 + 8611643 = 8611824

Showing the first eight; more decompositions exist.
