Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505768, here are decompositions:

5 + 505763 = 505768
41 + 505727 = 505768
59 + 505709 = 505768
149 + 505619 = 505768
167 + 505601 = 505768
257 + 505511 = 505768
359 + 505409 = 505768
401 + 505367 = 505768

Showing the first eight; more decompositions exist.
