Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511120, here are decompositions:

11 + 511109 = 511120
59 + 511061 = 511120
101 + 511019 = 511120
107 + 511013 = 511120
131 + 510989 = 511120
179 + 510941 = 511120
293 + 510827 = 511120
317 + 510803 = 511120

Showing the first eight; more decompositions exist.
