Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511392, here are decompositions:

5 + 511387 = 511392
31 + 511361 = 511392
41 + 511351 = 511392
59 + 511333 = 511392
103 + 511289 = 511392
113 + 511279 = 511392
131 + 511261 = 511392
149 + 511243 = 511392

Showing the first eight; more decompositions exist.
