Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551826, here are decompositions:

13 + 551813 = 551826
17 + 551809 = 551826
53 + 551773 = 551826
59 + 551767 = 551826
73 + 551753 = 551826
83 + 551743 = 551826
97 + 551729 = 551826
103 + 551723 = 551826

Showing the first eight; more decompositions exist.
