Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511556, here are decompositions:

7 + 511549 = 511556
37 + 511519 = 511556
79 + 511477 = 511556
103 + 511453 = 511556
109 + 511447 = 511556
139 + 511417 = 511556
223 + 511333 = 511556
229 + 511327 = 511556

Showing the first eight; more decompositions exist.
