Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558780, here are decompositions:

11 + 558769 = 558780
23 + 558757 = 558780
59 + 558721 = 558780
97 + 558683 = 558780
137 + 558643 = 558780
151 + 558629 = 558780
181 + 558599 = 558780
193 + 558587 = 558780

Showing the first eight; more decompositions exist.
