Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551100, here are decompositions:

7 + 551093 = 551100
31 + 551069 = 551100
37 + 551063 = 551100
41 + 551059 = 551100
61 + 551039 = 551100
73 + 551027 = 551100
83 + 551017 = 551100
97 + 551003 = 551100

Showing the first eight; more decompositions exist.
