Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551254, here are decompositions:

23 + 551231 = 551254
47 + 551207 = 551254
191 + 551063 = 551254
227 + 551027 = 551254
251 + 551003 = 551254
257 + 550997 = 551254
281 + 550973 = 551254
293 + 550961 = 551254

Showing the first eight; more decompositions exist.
