Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025906, here are decompositions:

19 + 1025887 = 1025906
67 + 1025839 = 1025906
103 + 1025803 = 1025906
139 + 1025767 = 1025906
157 + 1025749 = 1025906
199 + 1025707 = 1025906
283 + 1025623 = 1025906
397 + 1025509 = 1025906

Showing the first eight; more decompositions exist.
