Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001928, here are decompositions:

17 + 1001911 = 1001928
89 + 1001839 = 1001928
97 + 1001831 = 1001928
107 + 1001821 = 1001928
127 + 1001801 = 1001928
131 + 1001797 = 1001928
241 + 1001687 = 1001928
269 + 1001659 = 1001928

Showing the first eight; more decompositions exist.
