Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550818, here are decompositions:

5 + 550813 = 550818
7 + 550811 = 550818
17 + 550801 = 550818
29 + 550789 = 550818
61 + 550757 = 550818
97 + 550721 = 550818
101 + 550717 = 550818
127 + 550691 = 550818

Showing the first eight; more decompositions exist.
