Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740400, here are decompositions:

7 + 8740393 = 8740400
13 + 8740387 = 8740400
73 + 8740327 = 8740400
79 + 8740321 = 8740400
127 + 8740273 = 8740400
181 + 8740219 = 8740400
271 + 8740129 = 8740400
283 + 8740117 = 8740400

Showing the first eight; more decompositions exist.
