Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709640, here are decompositions:

29 + 8709611 = 8709640
53 + 8709587 = 8709640
113 + 8709527 = 8709640
131 + 8709509 = 8709640
179 + 8709461 = 8709640
197 + 8709443 = 8709640
257 + 8709383 = 8709640
263 + 8709377 = 8709640

Showing the first eight; more decompositions exist.
