Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690904, here are decompositions:

37 + 8690867 = 8690904
83 + 8690821 = 8690904
107 + 8690797 = 8690904
137 + 8690767 = 8690904
163 + 8690741 = 8690904
191 + 8690713 = 8690904
227 + 8690677 = 8690904
241 + 8690663 = 8690904

Showing the first eight; more decompositions exist.
