Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699828, here are decompositions:

97 + 8699731 = 8699828
271 + 8699557 = 8699828
409 + 8699419 = 8699828
439 + 8699389 = 8699828
601 + 8699227 = 8699828
661 + 8699167 = 8699828
751 + 8699077 = 8699828
859 + 8698969 = 8699828

Showing the first eight; more decompositions exist.
