Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699808, here are decompositions:

37 + 8699771 = 8699808
149 + 8699659 = 8699808
167 + 8699641 = 8699808
197 + 8699611 = 8699808
241 + 8699567 = 8699808
251 + 8699557 = 8699808
269 + 8699539 = 8699808
307 + 8699501 = 8699808

Showing the first eight; more decompositions exist.
