Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729922, here are decompositions:

41 + 8729881 = 8729922
53 + 8729869 = 8729922
73 + 8729849 = 8729922
83 + 8729839 = 8729922
101 + 8729821 = 8729922
193 + 8729729 = 8729922
211 + 8729711 = 8729922
233 + 8729689 = 8729922

Showing the first eight; more decompositions exist.
