Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551730, here are decompositions:

7 + 551723 = 551730
13 + 551717 = 551730
17 + 551713 = 551730
37 + 551693 = 551730
41 + 551689 = 551730
59 + 551671 = 551730
71 + 551659 = 551730
79 + 551651 = 551730

Showing the first eight; more decompositions exist.
