Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706740, here are decompositions:

13 + 8706727 = 8706740
73 + 8706667 = 8706740
127 + 8706613 = 8706740
193 + 8706547 = 8706740
277 + 8706463 = 8706740
283 + 8706457 = 8706740
337 + 8706403 = 8706740
373 + 8706367 = 8706740

Showing the first eight; more decompositions exist.
