Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558240, here are decompositions:

17 + 558223 = 558240
31 + 558209 = 558240
37 + 558203 = 558240
43 + 558197 = 558240
61 + 558179 = 558240
73 + 558167 = 558240
101 + 558139 = 558240
127 + 558113 = 558240

Showing the first eight; more decompositions exist.
