Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551376, here are decompositions:

13 + 551363 = 551376
29 + 551347 = 551376
37 + 551339 = 551376
79 + 551297 = 551376
107 + 551269 = 551376
157 + 551219 = 551376
179 + 551197 = 551376
197 + 551179 = 551376

Showing the first eight; more decompositions exist.
