Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729876, here are decompositions:

7 + 8729869 = 8729876
37 + 8729839 = 8729876
109 + 8729767 = 8729876
229 + 8729647 = 8729876
283 + 8729593 = 8729876
313 + 8729563 = 8729876
409 + 8729467 = 8729876
487 + 8729389 = 8729876

Showing the first eight; more decompositions exist.
