Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555920, here are decompositions:

67 + 555853 = 555920
97 + 555823 = 555920
181 + 555739 = 555920
223 + 555697 = 555920
229 + 555691 = 555920
283 + 555637 = 555920
331 + 555589 = 555920
397 + 555523 = 555920

Showing the first eight; more decompositions exist.
