Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005008, here are decompositions:

31 + 1004977 = 1005008
97 + 1004911 = 1005008
211 + 1004797 = 1005008
229 + 1004779 = 1005008
271 + 1004737 = 1005008
331 + 1004677 = 1005008
337 + 1004671 = 1005008
349 + 1004659 = 1005008

Showing the first eight; more decompositions exist.
