Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558656, here are decompositions:

13 + 558643 = 558656
73 + 558583 = 558656
127 + 558529 = 558656
157 + 558499 = 558656
199 + 558457 = 558656
229 + 558427 = 558656
313 + 558343 = 558656
337 + 558319 = 558656

Showing the first eight; more decompositions exist.
