Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551836, here are decompositions:

23 + 551813 = 551836
83 + 551753 = 551836
107 + 551729 = 551836
113 + 551723 = 551836
239 + 551597 = 551836
293 + 551543 = 551836
317 + 551519 = 551836
347 + 551489 = 551836

Showing the first eight; more decompositions exist.
