Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005386, here are decompositions:

13 + 1005373 = 1005386
37 + 1005349 = 1005386
73 + 1005313 = 1005386
157 + 1005229 = 1005386
163 + 1005223 = 1005386
199 + 1005187 = 1005386
307 + 1005079 = 1005386
313 + 1005073 = 1005386

Showing the first eight; more decompositions exist.
