Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551026, here are decompositions:

23 + 551003 = 551026
29 + 550997 = 551026
53 + 550973 = 551026
89 + 550937 = 551026
167 + 550859 = 551026
263 + 550763 = 551026
269 + 550757 = 551026
293 + 550733 = 551026

Showing the first eight; more decompositions exist.
