Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551070, here are decompositions:

7 + 551063 = 551070
11 + 551059 = 551070
31 + 551039 = 551070
43 + 551027 = 551070
53 + 551017 = 551070
67 + 551003 = 551070
73 + 550997 = 551070
97 + 550973 = 551070

Showing the first eight; more decompositions exist.
