Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552878, here are decompositions:

19 + 552859 = 552878
31 + 552847 = 552878
37 + 552841 = 552878
127 + 552751 = 552878
229 + 552649 = 552878
367 + 552511 = 552878
397 + 552481 = 552878
409 + 552469 = 552878

Showing the first eight; more decompositions exist.
