Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626400, here are decompositions:

103 + 8626297 = 8626400
151 + 8626249 = 8626400
157 + 8626243 = 8626400
163 + 8626237 = 8626400
241 + 8626159 = 8626400
271 + 8626129 = 8626400
337 + 8626063 = 8626400
421 + 8625979 = 8626400

Showing the first eight; more decompositions exist.
