Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551946, here are decompositions:

13 + 551933 = 551946
19 + 551927 = 551946
29 + 551917 = 551946
37 + 551909 = 551946
97 + 551849 = 551946
103 + 551843 = 551946
137 + 551809 = 551946
173 + 551773 = 551946

Showing the first eight; more decompositions exist.
