Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551260, here are decompositions:

29 + 551231 = 551260
41 + 551219 = 551260
53 + 551207 = 551260
131 + 551129 = 551260
167 + 551093 = 551260
191 + 551069 = 551260
197 + 551063 = 551260
233 + 551027 = 551260

Showing the first eight; more decompositions exist.
