Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551756, here are decompositions:

3 + 551753 = 551756
13 + 551743 = 551756
43 + 551713 = 551756
67 + 551689 = 551756
97 + 551659 = 551756
103 + 551653 = 551756
199 + 551557 = 551756
313 + 551443 = 551756

Showing the first eight; more decompositions exist.
