Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577880, here are decompositions:

7 + 577873 = 577880
13 + 577867 = 577880
31 + 577849 = 577880
73 + 577807 = 577880
241 + 577639 = 577880
307 + 577573 = 577880
349 + 577531 = 577880
367 + 577513 = 577880

Showing the first eight; more decompositions exist.
