Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501826, here are decompositions:

5 + 501821 = 501826
23 + 501803 = 501826
47 + 501779 = 501826
107 + 501719 = 501826
167 + 501659 = 501826
233 + 501593 = 501826
263 + 501563 = 501826
443 + 501383 = 501826

Showing the first eight; more decompositions exist.
