Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551890, here are decompositions:

29 + 551861 = 551890
41 + 551849 = 551890
47 + 551843 = 551890
89 + 551801 = 551890
137 + 551753 = 551890
167 + 551723 = 551890
173 + 551717 = 551890
197 + 551693 = 551890

Showing the first eight; more decompositions exist.
