Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551964, here are decompositions:

5 + 551959 = 551964
13 + 551951 = 551964
31 + 551933 = 551964
37 + 551927 = 551964
47 + 551917 = 551964
53 + 551911 = 551964
103 + 551861 = 551964
151 + 551813 = 551964

Showing the first eight; more decompositions exist.
