Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558440, here are decompositions:

13 + 558427 = 558440
19 + 558421 = 558440
97 + 558343 = 558440
151 + 558289 = 558440
199 + 558241 = 558440
331 + 558109 = 558440
349 + 558091 = 558440
373 + 558067 = 558440

Showing the first eight; more decompositions exist.
