Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664640, here are decompositions:

59 + 8664581 = 8664640
113 + 8664527 = 8664640
167 + 8664473 = 8664640
227 + 8664413 = 8664640
251 + 8664389 = 8664640
263 + 8664377 = 8664640
311 + 8664329 = 8664640
587 + 8664053 = 8664640

Showing the first eight; more decompositions exist.
