Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620400, here are decompositions:

7 + 8620393 = 8620400
31 + 8620369 = 8620400
73 + 8620327 = 8620400
181 + 8620219 = 8620400
211 + 8620189 = 8620400
241 + 8620159 = 8620400
331 + 8620069 = 8620400
337 + 8620063 = 8620400

Showing the first eight; more decompositions exist.
