Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551090, here are decompositions:

31 + 551059 = 551090
73 + 551017 = 551090
97 + 550993 = 551090
139 + 550951 = 551090
151 + 550939 = 551090
181 + 550909 = 551090
229 + 550861 = 551090
277 + 550813 = 551090

Showing the first eight; more decompositions exist.
