Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691490, here are decompositions:

11 + 8691479 = 8691490
83 + 8691407 = 8691490
107 + 8691383 = 8691490
131 + 8691359 = 8691490
191 + 8691299 = 8691490
239 + 8691251 = 8691490
251 + 8691239 = 8691490
281 + 8691209 = 8691490

Showing the first eight; more decompositions exist.
