Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664628, here are decompositions:

47 + 8664581 = 8664628
101 + 8664527 = 8664628
197 + 8664431 = 8664628
239 + 8664389 = 8664628
251 + 8664377 = 8664628
311 + 8664317 = 8664628
317 + 8664311 = 8664628
521 + 8664107 = 8664628

Showing the first eight; more decompositions exist.
