Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520700, here are decompositions:

67 + 520633 = 520700
79 + 520621 = 520700
151 + 520549 = 520700
277 + 520423 = 520700
307 + 520393 = 520700
331 + 520369 = 520700
337 + 520363 = 520700
409 + 520291 = 520700

Showing the first eight; more decompositions exist.
