Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555444, here are decompositions:

5 + 555439 = 555444
23 + 555421 = 555444
53 + 555391 = 555444
61 + 555383 = 555444
83 + 555361 = 555444
107 + 555337 = 555444
137 + 555307 = 555444
151 + 555293 = 555444

Showing the first eight; more decompositions exist.
