Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550840, here are decompositions:

29 + 550811 = 550840
83 + 550757 = 550840
107 + 550733 = 550840
137 + 550703 = 550840
149 + 550691 = 550840
179 + 550661 = 550840
233 + 550607 = 550840
263 + 550577 = 550840

Showing the first eight; more decompositions exist.
