Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577540, here are decompositions:

3 + 577537 = 577540
11 + 577529 = 577540
17 + 577523 = 577540
23 + 577517 = 577540
83 + 577457 = 577540
113 + 577427 = 577540
191 + 577349 = 577540
233 + 577307 = 577540

Showing the first eight; more decompositions exist.
