Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551008, here are decompositions:

5 + 551003 = 551008
11 + 550997 = 551008
47 + 550961 = 551008
71 + 550937 = 551008
149 + 550859 = 551008
167 + 550841 = 551008
197 + 550811 = 551008
251 + 550757 = 551008

Showing the first eight; more decompositions exist.
