Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551554, here are decompositions:

5 + 551549 = 551554
11 + 551543 = 551554
71 + 551483 = 551554
131 + 551423 = 551554
167 + 551387 = 551554
173 + 551381 = 551554
191 + 551363 = 551554
233 + 551321 = 551554

Showing the first eight; more decompositions exist.
