Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551884, here are decompositions:

23 + 551861 = 551884
41 + 551843 = 551884
71 + 551813 = 551884
83 + 551801 = 551884
131 + 551753 = 551884
167 + 551717 = 551884
191 + 551693 = 551884
233 + 551651 = 551884

Showing the first eight; more decompositions exist.
