Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709402, here are decompositions:

19 + 8709383 = 8709402
29 + 8709373 = 8709402
41 + 8709361 = 8709402
89 + 8709313 = 8709402
101 + 8709301 = 8709402
103 + 8709299 = 8709402
113 + 8709289 = 8709402
131 + 8709271 = 8709402

Showing the first eight; more decompositions exist.
