Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610090, here are decompositions:

23 + 8610067 = 8610090
29 + 8610061 = 8610090
89 + 8610001 = 8610090
103 + 8609987 = 8610090
127 + 8609963 = 8610090
163 + 8609927 = 8610090
173 + 8609917 = 8610090
179 + 8609911 = 8610090

Showing the first eight; more decompositions exist.
