Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577820, here are decompositions:

3 + 577817 = 577820
13 + 577807 = 577820
181 + 577639 = 577820
193 + 577627 = 577820
283 + 577537 = 577820
307 + 577513 = 577820
337 + 577483 = 577820
349 + 577471 = 577820

Showing the first eight; more decompositions exist.
