Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707400, here are decompositions:

7 + 8707393 = 8707400
43 + 8707357 = 8707400
67 + 8707333 = 8707400
73 + 8707327 = 8707400
127 + 8707273 = 8707400
181 + 8707219 = 8707400
193 + 8707207 = 8707400
211 + 8707189 = 8707400

Showing the first eight; more decompositions exist.
