Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555884, here are decompositions:

13 + 555871 = 555884
31 + 555853 = 555884
61 + 555823 = 555884
193 + 555691 = 555884
223 + 555661 = 555884
397 + 555487 = 555884
463 + 555421 = 555884
523 + 555361 = 555884

Showing the first eight; more decompositions exist.
