Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556448, here are decompositions:

7 + 556441 = 556448
97 + 556351 = 556448
127 + 556321 = 556448
181 + 556267 = 556448
229 + 556219 = 556448
271 + 556177 = 556448
379 + 556069 = 556448
397 + 556051 = 556448

Showing the first eight; more decompositions exist.
