Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558438, here are decompositions:

7 + 558431 = 558438
11 + 558427 = 558438
17 + 558421 = 558438
37 + 558401 = 558438
131 + 558307 = 558438
149 + 558289 = 558438
151 + 558287 = 558438
197 + 558241 = 558438

Showing the first eight; more decompositions exist.
