Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551678, here are decompositions:

7 + 551671 = 551678
19 + 551659 = 551678
97 + 551581 = 551678
109 + 551569 = 551678
139 + 551539 = 551678
271 + 551407 = 551678
331 + 551347 = 551678
367 + 551311 = 551678

Showing the first eight; more decompositions exist.
