Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551748, here are decompositions:

5 + 551743 = 551748
17 + 551731 = 551748
19 + 551729 = 551748
31 + 551717 = 551748
59 + 551689 = 551748
89 + 551659 = 551748
97 + 551651 = 551748
151 + 551597 = 551748

Showing the first eight; more decompositions exist.
