Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005050, here are decompositions:

31 + 1005019 = 1005050
37 + 1005013 = 1005050
43 + 1005007 = 1005050
73 + 1004977 = 1005050
139 + 1004911 = 1005050
271 + 1004779 = 1005050
307 + 1004743 = 1005050
313 + 1004737 = 1005050

Showing the first eight; more decompositions exist.
