Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701090, here are decompositions:

23 + 8701067 = 8701090
89 + 8701001 = 8701090
137 + 8700953 = 8701090
149 + 8700941 = 8701090
179 + 8700911 = 8701090
197 + 8700893 = 8701090
257 + 8700833 = 8701090
263 + 8700827 = 8701090

Showing the first eight; more decompositions exist.
