Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551172, here are decompositions:

29 + 551143 = 551172
43 + 551129 = 551172
59 + 551113 = 551172
73 + 551099 = 551172
79 + 551093 = 551172
103 + 551069 = 551172
109 + 551063 = 551172
113 + 551059 = 551172

Showing the first eight; more decompositions exist.
