Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551982, here are decompositions:

19 + 551963 = 551982
23 + 551959 = 551982
31 + 551951 = 551982
71 + 551911 = 551982
73 + 551909 = 551982
139 + 551843 = 551982
173 + 551809 = 551982
181 + 551801 = 551982

Showing the first eight; more decompositions exist.
