Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505888, here are decompositions:

11 + 505877 = 505888
17 + 505871 = 505888
107 + 505781 = 505888
179 + 505709 = 505888
197 + 505691 = 505888
269 + 505619 = 505888
281 + 505607 = 505888
419 + 505469 = 505888

Showing the first eight; more decompositions exist.
