Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551688, here are decompositions:

17 + 551671 = 551688
29 + 551659 = 551688
37 + 551651 = 551688
101 + 551587 = 551688
107 + 551581 = 551688
131 + 551557 = 551688
139 + 551549 = 551688
149 + 551539 = 551688

Showing the first eight; more decompositions exist.
