Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551988, here are decompositions:

7 + 551981 = 551988
29 + 551959 = 551988
37 + 551951 = 551988
61 + 551927 = 551988
71 + 551917 = 551988
79 + 551909 = 551988
127 + 551861 = 551988
139 + 551849 = 551988

Showing the first eight; more decompositions exist.
