Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666588, here are decompositions:

97 + 8666491 = 8666588
109 + 8666479 = 8666588
157 + 8666431 = 8666588
241 + 8666347 = 8666588
421 + 8666167 = 8666588
571 + 8666017 = 8666588
691 + 8665897 = 8666588
739 + 8665849 = 8666588

Showing the first eight; more decompositions exist.
