Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511554, here are decompositions:

5 + 511549 = 511554
13 + 511541 = 511554
31 + 511523 = 511554
47 + 511507 = 511554
67 + 511487 = 511554
97 + 511457 = 511554
101 + 511453 = 511554
107 + 511447 = 511554

Showing the first eight; more decompositions exist.
