Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664400, here are decompositions:

11 + 8664389 = 8664400
23 + 8664377 = 8664400
71 + 8664329 = 8664400
83 + 8664317 = 8664400
89 + 8664311 = 8664400
293 + 8664107 = 8664400
347 + 8664053 = 8664400
431 + 8663969 = 8664400

Showing the first eight; more decompositions exist.
