Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551816, here are decompositions:

3 + 551813 = 551816
7 + 551809 = 551816
43 + 551773 = 551816
73 + 551743 = 551816
103 + 551713 = 551816
127 + 551689 = 551816
157 + 551659 = 551816
163 + 551653 = 551816

Showing the first eight; more decompositions exist.
