Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551984, here are decompositions:

3 + 551981 = 551984
67 + 551917 = 551984
73 + 551911 = 551984
211 + 551773 = 551984
241 + 551743 = 551984
271 + 551713 = 551984
313 + 551671 = 551984
331 + 551653 = 551984

Showing the first eight; more decompositions exist.
