Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551452, here are decompositions:

29 + 551423 = 551452
71 + 551381 = 551452
89 + 551363 = 551452
113 + 551339 = 551452
131 + 551321 = 551452
233 + 551219 = 551452
353 + 551099 = 551452
359 + 551093 = 551452

Showing the first eight; more decompositions exist.
