Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727400, here are decompositions:

41 + 8727359 = 8727400
83 + 8727317 = 8727400
113 + 8727287 = 8727400
131 + 8727269 = 8727400
137 + 8727263 = 8727400
239 + 8727161 = 8727400
251 + 8727149 = 8727400
281 + 8727119 = 8727400

Showing the first eight; more decompositions exist.
