Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025366, here are decompositions:

19 + 1025347 = 1025366
109 + 1025257 = 1025366
127 + 1025239 = 1025366
157 + 1025209 = 1025366
163 + 1025203 = 1025366
229 + 1025137 = 1025366
337 + 1025029 = 1025366
379 + 1024987 = 1025366

Showing the first eight; more decompositions exist.
