Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551980, here are decompositions:

17 + 551963 = 551980
29 + 551951 = 551980
47 + 551933 = 551980
53 + 551927 = 551980
71 + 551909 = 551980
131 + 551849 = 551980
137 + 551843 = 551980
167 + 551813 = 551980

Showing the first eight; more decompositions exist.
