Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739740, here are decompositions:

19 + 8739721 = 8739740
67 + 8739673 = 8739740
73 + 8739667 = 8739740
103 + 8739637 = 8739740
157 + 8739583 = 8739740
211 + 8739529 = 8739740
241 + 8739499 = 8739740
277 + 8739463 = 8739740

Showing the first eight; more decompositions exist.
