Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510826, here are decompositions:

3 + 510823 = 510826
23 + 510803 = 510826
53 + 510773 = 510826
59 + 510767 = 510826
149 + 510677 = 510826
257 + 510569 = 510826
443 + 510383 = 510826
593 + 510233 = 510826

Showing the first eight; more decompositions exist.
