Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556488, here are decompositions:

5 + 556483 = 556488
11 + 556477 = 556488
29 + 556459 = 556488
47 + 556441 = 556488
89 + 556399 = 556488
137 + 556351 = 556488
157 + 556331 = 556488
167 + 556321 = 556488

Showing the first eight; more decompositions exist.
