Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555728, here are decompositions:

31 + 555697 = 555728
37 + 555691 = 555728
67 + 555661 = 555728
139 + 555589 = 555728
241 + 555487 = 555728
307 + 555421 = 555728
337 + 555391 = 555728
367 + 555361 = 555728

Showing the first eight; more decompositions exist.
