Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558786, here are decompositions:

5 + 558781 = 558786
17 + 558769 = 558786
29 + 558757 = 558786
83 + 558703 = 558786
103 + 558683 = 558786
157 + 558629 = 558786
199 + 558587 = 558786
223 + 558563 = 558786

Showing the first eight; more decompositions exist.
