Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611020, here are decompositions:

17 + 8611003 = 8611020
23 + 8610997 = 8611020
59 + 8610961 = 8611020
83 + 8610937 = 8611020
101 + 8610919 = 8611020
107 + 8610913 = 8611020
127 + 8610893 = 8611020
139 + 8610881 = 8611020

Showing the first eight; more decompositions exist.
