Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555018, here are decompositions:

41 + 554977 = 555018
59 + 554959 = 555018
67 + 554951 = 555018
127 + 554891 = 555018
131 + 554887 = 555018
179 + 554839 = 555018
181 + 554837 = 555018
197 + 554821 = 555018

Showing the first eight; more decompositions exist.
