Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555872, here are decompositions:

19 + 555853 = 555872
43 + 555829 = 555872
181 + 555691 = 555872
211 + 555661 = 555872
283 + 555589 = 555872
349 + 555523 = 555872
433 + 555439 = 555872
523 + 555349 = 555872

Showing the first eight; more decompositions exist.
