Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551948, here are decompositions:

31 + 551917 = 551948
37 + 551911 = 551948
139 + 551809 = 551948
181 + 551767 = 551948
277 + 551671 = 551948
367 + 551581 = 551948
379 + 551569 = 551948
409 + 551539 = 551948

Showing the first eight; more decompositions exist.
