Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551500, here are decompositions:

11 + 551489 = 551500
17 + 551483 = 551500
113 + 551387 = 551500
137 + 551363 = 551500
179 + 551321 = 551500
269 + 551231 = 551500
281 + 551219 = 551500
293 + 551207 = 551500

Showing the first eight; more decompositions exist.
