Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005986, here are decompositions:

73 + 1005913 = 1005986
103 + 1005883 = 1005986
277 + 1005709 = 1005986
307 + 1005679 = 1005986
349 + 1005637 = 1005986
367 + 1005619 = 1005986
433 + 1005553 = 1005986
547 + 1005439 = 1005986

Showing the first eight; more decompositions exist.
