Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577872, here are decompositions:

5 + 577867 = 577872
23 + 577849 = 577872
41 + 577831 = 577872
73 + 577799 = 577872
151 + 577721 = 577872
233 + 577639 = 577872
271 + 577601 = 577872
283 + 577589 = 577872

Showing the first eight; more decompositions exist.
