Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051826, here are decompositions:

7 + 1051819 = 1051826
37 + 1051789 = 1051826
67 + 1051759 = 1051826
79 + 1051747 = 1051826
109 + 1051717 = 1051826
163 + 1051663 = 1051826
277 + 1051549 = 1051826
283 + 1051543 = 1051826

Showing the first eight; more decompositions exist.
