Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551998, here are decompositions:

17 + 551981 = 551998
47 + 551951 = 551998
71 + 551927 = 551998
89 + 551909 = 551998
137 + 551861 = 551998
149 + 551849 = 551998
197 + 551801 = 551998
269 + 551729 = 551998

Showing the first eight; more decompositions exist.
