Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551904, here are decompositions:

43 + 551861 = 551904
61 + 551843 = 551904
103 + 551801 = 551904
131 + 551773 = 551904
137 + 551767 = 551904
151 + 551753 = 551904
173 + 551731 = 551904
181 + 551723 = 551904

Showing the first eight; more decompositions exist.
