Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551472, here are decompositions:

11 + 551461 = 551472
29 + 551443 = 551472
109 + 551363 = 551472
151 + 551321 = 551472
191 + 551281 = 551472
239 + 551233 = 551472
241 + 551231 = 551472
293 + 551179 = 551472

Showing the first eight; more decompositions exist.
