Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551198, here are decompositions:

19 + 551179 = 551198
139 + 551059 = 551198
181 + 551017 = 551198
229 + 550969 = 551198
337 + 550861 = 551198
367 + 550831 = 551198
397 + 550801 = 551198
409 + 550789 = 551198

Showing the first eight; more decompositions exist.
