Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702740, here are decompositions:

41 + 8702699 = 8702740
47 + 8702693 = 8702740
149 + 8702591 = 8702740
197 + 8702543 = 8702740
251 + 8702489 = 8702740
257 + 8702483 = 8702740
281 + 8702459 = 8702740
353 + 8702387 = 8702740

Showing the first eight; more decompositions exist.
