Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551360, here are decompositions:

13 + 551347 = 551360
79 + 551281 = 551360
127 + 551233 = 551360
163 + 551197 = 551360
181 + 551179 = 551360
367 + 550993 = 551360
409 + 550951 = 551360
421 + 550939 = 551360

Showing the first eight; more decompositions exist.
