Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558490, here are decompositions:

11 + 558479 = 558490
17 + 558473 = 558490
59 + 558431 = 558490
89 + 558401 = 558490
239 + 558251 = 558490
281 + 558209 = 558490
293 + 558197 = 558490
311 + 558179 = 558490

Showing the first eight; more decompositions exist.
