Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551790, here are decompositions:

17 + 551773 = 551790
23 + 551767 = 551790
37 + 551753 = 551790
47 + 551743 = 551790
59 + 551731 = 551790
61 + 551729 = 551790
67 + 551723 = 551790
73 + 551717 = 551790

Showing the first eight; more decompositions exist.
