Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005826, here are decompositions:

5 + 1005821 = 1005826
149 + 1005677 = 1005826
179 + 1005647 = 1005826
233 + 1005593 = 1005826
359 + 1005467 = 1005826
389 + 1005437 = 1005826
467 + 1005359 = 1005826
509 + 1005317 = 1005826

Showing the first eight; more decompositions exist.
