Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026458, here are decompositions:

19 + 1026439 = 1026458
31 + 1026427 = 1026458
67 + 1026391 = 1026458
127 + 1026331 = 1026458
229 + 1026229 = 1026458
241 + 1026217 = 1026458
331 + 1026127 = 1026458
397 + 1026061 = 1026458

Showing the first eight; more decompositions exist.
