Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611506, here are decompositions:

5 + 8611501 = 8611506
19 + 8611487 = 8611506
67 + 8611439 = 8611506
73 + 8611433 = 8611506
83 + 8611423 = 8611506
103 + 8611403 = 8611506
107 + 8611399 = 8611506
149 + 8611357 = 8611506

Showing the first eight; more decompositions exist.
