Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729902, here are decompositions:

53 + 8729849 = 8729902
101 + 8729801 = 8729902
173 + 8729729 = 8729902
191 + 8729711 = 8729902
281 + 8729621 = 8729902
359 + 8729543 = 8729902
491 + 8729411 = 8729902
569 + 8729333 = 8729902

Showing the first eight; more decompositions exist.
