Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551824, here are decompositions:

11 + 551813 = 551824
23 + 551801 = 551824
71 + 551753 = 551824
101 + 551723 = 551824
107 + 551717 = 551824
131 + 551693 = 551824
173 + 551651 = 551824
227 + 551597 = 551824

Showing the first eight; more decompositions exist.
