Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611528, here are decompositions:

5 + 8611523 = 8611528
41 + 8611487 = 8611528
89 + 8611439 = 8611528
179 + 8611349 = 8611528
197 + 8611331 = 8611528
227 + 8611301 = 8611528
281 + 8611247 = 8611528
347 + 8611181 = 8611528

Showing the first eight; more decompositions exist.
