Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557998, here are decompositions:

11 + 557987 = 557998
17 + 557981 = 557998
71 + 557927 = 557998
107 + 557891 = 557998
137 + 557861 = 557998
167 + 557831 = 557998
197 + 557801 = 557998
239 + 557759 = 557998

Showing the first eight; more decompositions exist.
