Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709090, here are decompositions:

11 + 8709079 = 8709090
23 + 8709067 = 8709090
31 + 8709059 = 8709090
83 + 8709007 = 8709090
127 + 8708963 = 8709090
179 + 8708911 = 8709090
197 + 8708893 = 8709090
241 + 8708849 = 8709090

Showing the first eight; more decompositions exist.
