Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556446, here are decompositions:

5 + 556441 = 556446
43 + 556403 = 556446
47 + 556399 = 556446
73 + 556373 = 556446
103 + 556343 = 556446
157 + 556289 = 556446
167 + 556279 = 556446
173 + 556273 = 556446

Showing the first eight; more decompositions exist.
