Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577440, here are decompositions:

13 + 577427 = 577440
41 + 577399 = 577440
43 + 577397 = 577440
53 + 577387 = 577440
89 + 577351 = 577440
107 + 577333 = 577440
109 + 577331 = 577440
113 + 577327 = 577440

Showing the first eight; more decompositions exist.
