Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555578, here are decompositions:

139 + 555439 = 555578
157 + 555421 = 555578
229 + 555349 = 555578
241 + 555337 = 555578
271 + 555307 = 555578
277 + 555301 = 555578
487 + 555091 = 555578
601 + 554977 = 555578

Showing the first eight; more decompositions exist.
