Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511544, here are decompositions:

3 + 511541 = 511544
37 + 511507 = 511544
67 + 511477 = 511544
97 + 511447 = 511544
127 + 511417 = 511544
157 + 511387 = 511544
193 + 511351 = 511544
211 + 511333 = 511544

Showing the first eight; more decompositions exist.
