Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551786, here are decompositions:

13 + 551773 = 551786
19 + 551767 = 551786
43 + 551743 = 551786
73 + 551713 = 551786
97 + 551689 = 551786
127 + 551659 = 551786
199 + 551587 = 551786
229 + 551557 = 551786

Showing the first eight; more decompositions exist.
