Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005028, here are decompositions:

41 + 1004987 = 1005028
47 + 1004981 = 1005028
281 + 1004747 = 1005028
359 + 1004669 = 1005028
461 + 1004567 = 1005028
467 + 1004561 = 1005028
491 + 1004537 = 1005028
587 + 1004441 = 1005028

Showing the first eight; more decompositions exist.
