Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551436, here are decompositions:

13 + 551423 = 551436
29 + 551407 = 551436
73 + 551363 = 551436
89 + 551347 = 551436
97 + 551339 = 551436
139 + 551297 = 551436
167 + 551269 = 551436
229 + 551207 = 551436

Showing the first eight; more decompositions exist.
