Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005398, here are decompositions:

7 + 1005391 = 1005398
67 + 1005331 = 1005398
157 + 1005241 = 1005398
181 + 1005217 = 1005398
211 + 1005187 = 1005398
349 + 1005049 = 1005398
379 + 1005019 = 1005398
421 + 1004977 = 1005398

Showing the first eight; more decompositions exist.
