Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611040, here are decompositions:

3 + 8611037 = 8611040
7 + 8611033 = 8611040
37 + 8611003 = 8611040
43 + 8610997 = 8611040
79 + 8610961 = 8611040
103 + 8610937 = 8611040
127 + 8610913 = 8611040
211 + 8610829 = 8611040

Showing the first eight; more decompositions exist.
