Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551908, here are decompositions:

47 + 551861 = 551908
59 + 551849 = 551908
107 + 551801 = 551908
179 + 551729 = 551908
191 + 551717 = 551908
257 + 551651 = 551908
311 + 551597 = 551908
359 + 551549 = 551908

Showing the first eight; more decompositions exist.
