Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729964, here are decompositions:

41 + 8729923 = 8729964
83 + 8729881 = 8729964
97 + 8729867 = 8729964
127 + 8729837 = 8729964
163 + 8729801 = 8729964
197 + 8729767 = 8729964
283 + 8729681 = 8729964
317 + 8729647 = 8729964

Showing the first eight; more decompositions exist.
