Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550870, here are decompositions:

11 + 550859 = 550870
29 + 550841 = 550870
59 + 550811 = 550870
107 + 550763 = 550870
113 + 550757 = 550870
137 + 550733 = 550870
149 + 550721 = 550870
167 + 550703 = 550870

Showing the first eight; more decompositions exist.
