Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709618, here are decompositions:

7 + 8709611 = 8709618
31 + 8709587 = 8709618
109 + 8709509 = 8709618
149 + 8709469 = 8709618
157 + 8709461 = 8709618
241 + 8709377 = 8709618
257 + 8709361 = 8709618
317 + 8709301 = 8709618

Showing the first eight; more decompositions exist.
