Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555904, here are decompositions:

47 + 555857 = 555904
137 + 555767 = 555904
197 + 555707 = 555904
227 + 555677 = 555904
233 + 555671 = 555904
311 + 555593 = 555904
347 + 555557 = 555904
383 + 555521 = 555904

Showing the first eight; more decompositions exist.
