Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551488, here are decompositions:

5 + 551483 = 551488
101 + 551387 = 551488
107 + 551381 = 551488
149 + 551339 = 551488
167 + 551321 = 551488
191 + 551297 = 551488
257 + 551231 = 551488
269 + 551219 = 551488

Showing the first eight; more decompositions exist.
