Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729776, here are decompositions:

47 + 8729729 = 8729776
59 + 8729717 = 8729776
173 + 8729603 = 8729776
233 + 8729543 = 8729776
347 + 8729429 = 8729776
443 + 8729333 = 8729776
449 + 8729327 = 8729776
467 + 8729309 = 8729776

Showing the first eight; more decompositions exist.
