Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551072, here are decompositions:

3 + 551069 = 551072
13 + 551059 = 551072
79 + 550993 = 551072
103 + 550969 = 551072
163 + 550909 = 551072
211 + 550861 = 551072
229 + 550843 = 551072
241 + 550831 = 551072

Showing the first eight; more decompositions exist.
