Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022906, here are decompositions:

7 + 1022899 = 1022906
37 + 1022869 = 1022906
109 + 1022797 = 1022906
223 + 1022683 = 1022906
229 + 1022677 = 1022906
277 + 1022629 = 1022906
397 + 1022509 = 1022906
439 + 1022467 = 1022906

Showing the first eight; more decompositions exist.
