Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511404, here are decompositions:

13 + 511391 = 511404
17 + 511387 = 511404
43 + 511361 = 511404
53 + 511351 = 511404
67 + 511337 = 511404
71 + 511333 = 511404
107 + 511297 = 511404
167 + 511237 = 511404

Showing the first eight; more decompositions exist.
