Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709438, here are decompositions:

7 + 8709431 = 8709438
61 + 8709377 = 8709438
137 + 8709301 = 8709438
139 + 8709299 = 8709438
149 + 8709289 = 8709438
167 + 8709271 = 8709438
181 + 8709257 = 8709438
251 + 8709187 = 8709438

Showing the first eight; more decompositions exist.
