Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709520, here are decompositions:

11 + 8709509 = 8709520
59 + 8709461 = 8709520
89 + 8709431 = 8709520
137 + 8709383 = 8709520
263 + 8709257 = 8709520
461 + 8709059 = 8709520
557 + 8708963 = 8709520
857 + 8708663 = 8709520

Showing the first eight; more decompositions exist.
