Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558842, here are decompositions:

13 + 558829 = 558842
61 + 558781 = 558842
73 + 558769 = 558842
139 + 558703 = 558842
181 + 558661 = 558842
199 + 558643 = 558842
313 + 558529 = 558842
373 + 558469 = 558842

Showing the first eight; more decompositions exist.
