Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555256, here are decompositions:

3 + 555253 = 555256
5 + 555251 = 555256
47 + 555209 = 555256
89 + 555167 = 555256
113 + 555143 = 555256
137 + 555119 = 555256
173 + 555083 = 555256
179 + 555077 = 555256

Showing the first eight; more decompositions exist.
