Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551728, here are decompositions:

5 + 551723 = 551728
11 + 551717 = 551728
131 + 551597 = 551728
179 + 551549 = 551728
239 + 551489 = 551728
347 + 551381 = 551728
389 + 551339 = 551728
431 + 551297 = 551728

Showing the first eight; more decompositions exist.
