Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551162, here are decompositions:

19 + 551143 = 551162
103 + 551059 = 551162
193 + 550969 = 551162
211 + 550951 = 551162
223 + 550939 = 551162
331 + 550831 = 551162
349 + 550813 = 551162
373 + 550789 = 551162

Showing the first eight; more decompositions exist.
