Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729906, here are decompositions:

19 + 8729887 = 8729906
37 + 8729869 = 8729906
67 + 8729839 = 8729906
139 + 8729767 = 8729906
277 + 8729629 = 8729906
313 + 8729593 = 8729906
349 + 8729557 = 8729906
439 + 8729467 = 8729906

Showing the first eight; more decompositions exist.
