Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520802, here are decompositions:

43 + 520759 = 520802
103 + 520699 = 520802
181 + 520621 = 520802
193 + 520609 = 520802
379 + 520423 = 520802
409 + 520393 = 520802
421 + 520381 = 520802
433 + 520369 = 520802

Showing the first eight; more decompositions exist.
