Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555806, here are decompositions:

67 + 555739 = 555806
109 + 555697 = 555806
283 + 555523 = 555806
367 + 555439 = 555806
457 + 555349 = 555806
499 + 555307 = 555806
709 + 555097 = 555806
733 + 555073 = 555806

Showing the first eight; more decompositions exist.
