Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729884, here are decompositions:

3 + 8729881 = 8729884
17 + 8729867 = 8729884
47 + 8729837 = 8729884
83 + 8729801 = 8729884
167 + 8729717 = 8729884
173 + 8729711 = 8729884
263 + 8729621 = 8729884
281 + 8729603 = 8729884

Showing the first eight; more decompositions exist.
