Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558554, here are decompositions:

13 + 558541 = 558554
97 + 558457 = 558554
127 + 558427 = 558554
211 + 558343 = 558554
313 + 558241 = 558554
331 + 558223 = 558554
433 + 558121 = 558554
463 + 558091 = 558554

Showing the first eight; more decompositions exist.
