Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577666, here are decompositions:

29 + 577637 = 577666
53 + 577613 = 577666
107 + 577559 = 577666
137 + 577529 = 577666
149 + 577517 = 577666
239 + 577427 = 577666
269 + 577397 = 577666
317 + 577349 = 577666

Showing the first eight; more decompositions exist.
