Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577420, here are decompositions:

23 + 577397 = 577420
71 + 577349 = 577420
89 + 577331 = 577420
113 + 577307 = 577420
149 + 577271 = 577420
227 + 577193 = 577420
251 + 577169 = 577420
269 + 577151 = 577420

Showing the first eight; more decompositions exist.
