Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709740, here are decompositions:

3 + 8709737 = 8709740
19 + 8709721 = 8709740
43 + 8709697 = 8709740
271 + 8709469 = 8709740
367 + 8709373 = 8709740
379 + 8709361 = 8709740
439 + 8709301 = 8709740
601 + 8709139 = 8709740

Showing the first eight; more decompositions exist.
