Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551588, here are decompositions:

7 + 551581 = 551588
19 + 551569 = 551588
31 + 551557 = 551588
127 + 551461 = 551588
181 + 551407 = 551588
241 + 551347 = 551588
277 + 551311 = 551588
307 + 551281 = 551588

Showing the first eight; more decompositions exist.
