Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699688, here are decompositions:

29 + 8699659 = 8699688
47 + 8699641 = 8699688
131 + 8699557 = 8699688
149 + 8699539 = 8699688
199 + 8699489 = 8699688
269 + 8699419 = 8699688
307 + 8699381 = 8699688
337 + 8699351 = 8699688

Showing the first eight; more decompositions exist.
