Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551940, here are decompositions:

7 + 551933 = 551940
13 + 551927 = 551940
23 + 551917 = 551940
29 + 551911 = 551940
31 + 551909 = 551940
79 + 551861 = 551940
97 + 551843 = 551940
127 + 551813 = 551940

Showing the first eight; more decompositions exist.
