Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026440, here are decompositions:

13 + 1026427 = 1026440
109 + 1026331 = 1026440
127 + 1026313 = 1026440
211 + 1026229 = 1026440
223 + 1026217 = 1026440
241 + 1026199 = 1026440
313 + 1026127 = 1026440
367 + 1026073 = 1026440

Showing the first eight; more decompositions exist.
