Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511718, here are decompositions:

7 + 511711 = 511718
127 + 511591 = 511718
139 + 511579 = 511718
199 + 511519 = 511718
211 + 511507 = 511718
241 + 511477 = 511718
271 + 511447 = 511718
331 + 511387 = 511718

Showing the first eight; more decompositions exist.
