Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505826, here are decompositions:

3 + 505823 = 505826
7 + 505819 = 505826
67 + 505759 = 505826
157 + 505669 = 505826
163 + 505663 = 505826
193 + 505633 = 505826
313 + 505513 = 505826
367 + 505459 = 505826

Showing the first eight; more decompositions exist.
