Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001828, here are decompositions:

7 + 1001821 = 1001828
19 + 1001809 = 1001828
31 + 1001797 = 1001828
199 + 1001629 = 1001828
241 + 1001587 = 1001828
277 + 1001551 = 1001828
337 + 1001491 = 1001828
397 + 1001431 = 1001828

Showing the first eight; more decompositions exist.
