Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511398, here are decompositions:

7 + 511391 = 511398
11 + 511387 = 511398
37 + 511361 = 511398
47 + 511351 = 511398
61 + 511337 = 511398
71 + 511327 = 511398
101 + 511297 = 511398
109 + 511289 = 511398

Showing the first eight; more decompositions exist.
