Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026388, here are decompositions:

5 + 1026383 = 1026388
17 + 1026371 = 1026388
29 + 1026359 = 1026388
89 + 1026299 = 1026388
131 + 1026257 = 1026388
137 + 1026251 = 1026388
191 + 1026197 = 1026388
269 + 1026119 = 1026388

Showing the first eight; more decompositions exist.
