Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006398, here are decompositions:

5 + 1006393 = 1006398
7 + 1006391 = 1006398
31 + 1006367 = 1006398
37 + 1006361 = 1006398
47 + 1006351 = 1006398
59 + 1006339 = 1006398
61 + 1006337 = 1006398
67 + 1006331 = 1006398

Showing the first eight; more decompositions exist.
