Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026378, here are decompositions:

7 + 1026371 = 1026378
19 + 1026359 = 1026378
47 + 1026331 = 1026378
79 + 1026299 = 1026378
127 + 1026251 = 1026378
149 + 1026229 = 1026378
151 + 1026227 = 1026378
179 + 1026199 = 1026378

Showing the first eight; more decompositions exist.
