Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551830, here are decompositions:

17 + 551813 = 551830
29 + 551801 = 551830
101 + 551729 = 551830
107 + 551723 = 551830
113 + 551717 = 551830
137 + 551693 = 551830
179 + 551651 = 551830
233 + 551597 = 551830

Showing the first eight; more decompositions exist.
