Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556090, here are decompositions:

23 + 556067 = 556090
47 + 556043 = 556090
53 + 556037 = 556090
83 + 556007 = 556090
137 + 555953 = 556090
149 + 555941 = 556090
233 + 555857 = 556090
263 + 555827 = 556090

Showing the first eight; more decompositions exist.
