Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662090, here are decompositions:

11 + 8662079 = 8662090
53 + 8662037 = 8662090
71 + 8662019 = 8662090
113 + 8661977 = 8662090
137 + 8661953 = 8662090
149 + 8661941 = 8662090
191 + 8661899 = 8662090
251 + 8661839 = 8662090

Showing the first eight; more decompositions exist.
