Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551726, here are decompositions:

3 + 551723 = 551726
13 + 551713 = 551726
37 + 551689 = 551726
67 + 551659 = 551726
73 + 551653 = 551726
139 + 551587 = 551726
157 + 551569 = 551726
223 + 551503 = 551726

Showing the first eight; more decompositions exist.
