Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647400, here are decompositions:

7 + 8647393 = 8647400
31 + 8647369 = 8647400
127 + 8647273 = 8647400
271 + 8647129 = 8647400
277 + 8647123 = 8647400
337 + 8647063 = 8647400
373 + 8647027 = 8647400
379 + 8647021 = 8647400

Showing the first eight; more decompositions exist.
