Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665528, here are decompositions:

29 + 8665499 = 8665528
59 + 8665469 = 8665528
167 + 8665361 = 8665528
251 + 8665277 = 8665528
269 + 8665259 = 8665528
419 + 8665109 = 8665528
569 + 8664959 = 8665528
587 + 8664941 = 8665528

Showing the first eight; more decompositions exist.
