Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745400, here are decompositions:

47 + 8745353 = 8745400
71 + 8745329 = 8745400
89 + 8745311 = 8745400
101 + 8745299 = 8745400
173 + 8745227 = 8745400
197 + 8745203 = 8745400
239 + 8745161 = 8745400
281 + 8745119 = 8745400

Showing the first eight; more decompositions exist.
