Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628004, here are decompositions:

17 + 8627987 = 8628004
101 + 8627903 = 8628004
107 + 8627897 = 8628004
137 + 8627867 = 8628004
191 + 8627813 = 8628004
197 + 8627807 = 8628004
227 + 8627777 = 8628004
263 + 8627741 = 8628004

Showing the first eight; more decompositions exist.
