Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555280, here are decompositions:

3 + 555277 = 555280
23 + 555257 = 555280
29 + 555251 = 555280
59 + 555221 = 555280
71 + 555209 = 555280
113 + 555167 = 555280
137 + 555143 = 555280
197 + 555083 = 555280

Showing the first eight; more decompositions exist.
