Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550786, here are decompositions:

23 + 550763 = 550786
29 + 550757 = 550786
53 + 550733 = 550786
83 + 550703 = 550786
107 + 550679 = 550786
149 + 550637 = 550786
179 + 550607 = 550786
233 + 550553 = 550786

Showing the first eight; more decompositions exist.
