Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005002, here are decompositions:

223 + 1004779 = 1005002
241 + 1004761 = 1005002
331 + 1004671 = 1005002
541 + 1004461 = 1005002
601 + 1004401 = 1005002
631 + 1004371 = 1005002
709 + 1004293 = 1005002
769 + 1004233 = 1005002

Showing the first eight; more decompositions exist.
