Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520426, here are decompositions:

3 + 520423 = 520426
17 + 520409 = 520426
47 + 520379 = 520426
113 + 520313 = 520426
233 + 520193 = 520426
353 + 520073 = 520426
359 + 520067 = 520426
383 + 520043 = 520426

Showing the first eight; more decompositions exist.
