Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558380, here are decompositions:

37 + 558343 = 558380
61 + 558319 = 558380
73 + 558307 = 558380
127 + 558253 = 558380
139 + 558241 = 558380
157 + 558223 = 558380
241 + 558139 = 558380
271 + 558109 = 558380

Showing the first eight; more decompositions exist.
